The Trouble with Tramp Oil
11/1/2012
John M. Burke
Online Only Articles
Tramp oils are any unwanted oil that enters into a metalworking fluid during the manufacturing process. These oils can enter from a variety of sources such as oil on parts from previous operations, or leaks from hydraulic, way, spindle and gear oils. So my coolant or cutting already has oil in it, so won’t a little extra oils help? The simple answer to this question is …not likely.

Strategic Oil Analysis: Time Dependent Alarms for Extended Lubricant Lifecycles
8/2/2010
Mike Johnson
Featured Articles
TLT: Oil analysis is a powerful tool in the machine condition monitoring
toolbox—if used properly. Much like other technologies, it performs
best within a well-developed plan. When accomplished, a well-devised
plan can provide an effective long-term view into the health of any machine
with lubricated components.
TLT has provided STLE members with information about test methods,
alarm methods and about the best alarm fit for the noted test methods to
construct an effective oil analysis approach. The November 2009 TLT provides
an overview that would be a worthwhile preview to this article. This
article can be found on the STLE Web site.
The 2009 article indicates that there are three common alarm types for
grading the underlying problems for sumps and lubricated components.These are statistical (alarms used to identify machine wear problems), absolute (aka aging alarms, used to identify lubricant
health and degradation) and percentage-based alarms(used for lubricant health and contamination monitoring).

Faster, more durable lithium-ion batteries
6/1/2010
Dr. Neil Canter
Featured Articles
The potential for using lithium-ion batteries in a number of applications is due to their superior performance, which includes lower power loss compared to other battery types. But problems have been encountered with slow cycling (charge and discharge) rates of lithium ions and safety. In the latter case, lithium-ion batteries have been found to catch on fire during use.
In a previous TLT article, a layered lithium battery was developed featuring a
transitional cathodic material, which contains high levels of nickel in the core and high concentrations of manganese on the surface. The former generates high energy but is unstable while the latter is more stable. This cathode material provides the combination of high energy with better stability.

Tribology & Lubricants Fundamentals Column, TLT
In previous articles I have discussed the business and technical
aspects of the wind energy movement. Indeed, the wind energy movement has certainly demonstrated that it
has legs. There is a great deal of research funding dedicated to solving or resolving many of the technical issues affecting this industry. Many STLE members are enjoying this largesse. These issues are intriguing and challenging—good work for tribologists and lubrication engineers. By the way, if
you want to learn more about how STLE members perceive the challenges of wind turbines, please see the Sounding
Board article in last month’s issue of TLT.

Real-world oil analysis: Part III
5/1/2010
Jack Poley
Featured Articles
Continuing our exploration of real-world oil analysis, here is a collection of four sets of data from a final drive
(planetary gearset) on an earth mover that really presents no evaluation mystery at the macro level. Get rid of the dirt and water, flush out the sump best one can, resolve the reason
(seal compromise, lube-handling practices or one-off extrahostile
environmental or usage conditions) and have a fairly healthy gear system—assuming it hasn’t failed from neglect
since the problem was detected two samples earlier.
The lube was changed one sample ago; that’s drained, as in the entirety of the work that was done. This customer
evidently believes or hopes that changing the oil makes the problem go away, as no maintenance effort beyond the
change was undertaken, nor was a system flush attempted. Well, at least the numbers got smaller.

Gas-expanded lubricants
5/1/2010
Dr. Neil Canter
Featured Articles
Gas-expanded liquids have been widely studied in the chemical sector for a
variety of applications since the 1990s. According to Andres Clarens, assistant
professor of civil and environmental engineering at the University of Virginia
in Charlottesville, Va., “These liquids are often a mixture of a gas such as carbondioxide and a solvent under elevated pressures. By controlling the pressure and the temperature of the mixture, it is possible to carefully specify the properties of the fluid, which has important implications in a lot of applications where tunability is desired.”
These mixtures make for easy separation of carbon dioxide from a solvent. Clarens
indicates that one other benefit is that these mixtures reduce the total amount
of solvent required for a specific operation. He says, “Adding carbon dioxide reduces the amount of solvent required for a specific application, and this lowers the cost and reduces the environmental footprint.”

Drop friction
4/1/2010
Dr. Neil Canter
Featured Articles
A better understanding of friction at the macroscale and the nanoscale has been
the subject of much research and a number of articles in TLT. We all know
that a solid object placed on a surface can be moved once frictional forces are overcome.
The force needed to push the object is proportional to the object’s weight or
load. A heavier object has a greater contact area with the surface than a lighter one and, as a result, has more friction to overcome in order to move. This is the basis for Amontons’ laws of friction.
In a previous TLT article, work was done to show that friction at the nanoscale
is consistent with what is seen at the macroscale. Both effects are dependent upon the roughness of the surface. In the case of the nanoscale, roughness is defined by the number of atoms that interact between two surfaces.

MWF heat treatment: Options for a critical process
3/1/2010
Dr. Neil Canter
Featured Articles
When the topic of metalworking is raised, most of us think of drilling a hole in a piece of metal or bending a metal part to form a component for an
automobile. Not as many individuals realize that another process included under the realm of metalworking is heat treating or quenching.
Heat treatment is utilized to adjust the physical and mechanical properties of
metals so that they can be used in subsequent metalworking applications. These properties are changed by the controlled heating and then cooling of metals. In many cases, the objective of heat treatment is to increase the strength of a specific metal
alloy. Most operations are conducted on steel alloys, but nonferrous metals such as aluminum and titanium also can be heat treated.

Real-world oil analysis
3/1/2010
Jack Poley
Featured Articles
Let’s continue our discussion on concepts in oil analysis data evaluation from a worm gear drive in an industrial
manufacturing plant. There are 17 reports available for this component, as we’ll inspect the most recent samples to present, as shown in Figure 1.
At first glance this looks sudden but, looking at the Fe pattern now, we can see that the two previous samples were
predictive of the wear event in the most current sample, perhaps not as boring as I claimed. Si (silicon) has dramatically
increased, as well and, with no evidence to the contrary, is likely indicative of abrasive contamination.

Feel of skin cream
3/1/2010
Dr. Neil Canter
Featured Articles
As an old surfactant chemist, I found out early in my career that there is a
direct relationship between the components used in personal-care products
and in lubricants. Formulators in both markets share components such as emulsifiers and lubricity additives. The latter are known to the personal-care industry as emollients.
One personal-care product that we use everyday is skin cream. While we may
not pay much attention to the product’s content, skin creams are complex emulsions that contain such additive types as humectants (attract and hold water in the skin) and occlusives (form a layer on the skin surface and moisturize by retarding water evaporation). In a sense, a skin cream has comparable components to an
emulsified oil used in metalworking applications.

Supercritical fuel
2/1/2010
Dr. Neil Canter
Featured Articles
A wide range of approaches have been undertaken to determine how to reduce
emissions from automotive engines. In a previous TLT article, the development
of the homogeneous charge compression ignition (HCCI) engine was discussed.
When used in place of a conventional gasoline engine, an HCCI engine can
produce a 15% to 20% improvement in fuel economy and a significant reduction in
NOx emissions. The HCCI process relies on spontaneous ignition of the gasoline,
air mixture similar to the auto-ignition process in a diesel engine.
As we all know, three specific states of matter (solid, liquid and gas) exist, and
most substances can be found in one of these states at any given combination of
temperature and pressure. When the temperature and pressure is increased above a value known as the critical point, the substance reaches a fourth state known as supercritical.

Stretching salt
1/1/2010
Dr. Neil Canter
Featured Articles
Salt or sodium chloride is a typical ionic solid that we all know well from both personal and professional perspectives. This compound contains sodium and chlorine ions organized in face-centered cubic crystals. Electrostatic interactions
between these ions are the source of the bonding that holds this compound together.
The presence of salt as a contaminant is a concern because it promotes metal
corrosion. Salt is readily soluble in water and facilitates the movement of ions through metal, which accelerates the corrosion process.
Salt is also a brittle material that readily shatters like glass when placed under pressure. But when placed in a humid environment, salt becomes more ductile. Nathan Moore, postdoctoral researcher at Sandia National Laboratories in Albuquerque,
N.M., says, “It is possible to bend and twist large pieces of salt as long as they are not just single crystals but are made of smaller grains.”

Improved solar power reflector
12/1/2009
Dr. Neil Canter
Featured Articles
Development of alternative energy sources has been a daunting task from both the technology and economic standpoints. A case in point is capturing solar energy for use in generating electricity.
In a previous TLT article, a heat transfer fluid is found to be an integral component in a parabolic mirror used to capture solar energy for the generation of electricity. The parabolic mirror efficiently captures and focuses solar rays onto a receiver pipe containing a heat transfer fluid.
Keith Gawlik, senior engineer at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL), says, “The use of parabolic mirrors to capture solar energy dates back to the first installations in the 1980s. In a period between 1984 and 1991, the Solar Electric Generating Systems (SEGS) was established in the U.S. in the Mojave Desert in California. SEGS includes nine plants with a total capacity of 354 megawatts.”

Nanoparticle-based emission catalysts
11/1/2009
Dr. Neil Canter
Featured Articles
Reducing automotive emissions increases the need for more effective catalyst
technologies. In the U.S., EPA has reduced the NOx emission requirements to
1.2 grams per brake hp hour in 2007. This emissions requirement will drop further
to 0.2 gram per brake hp hour in 2010.
In a past column, the benefits of a cerium oxide-modified Cu-ZSM-5 catalyst
were described in reducing NOx emissions. The introduction of cerium oxide enabled
the catalyst to function in the temperature range (between 325 C and 350 C)
of diesel exhaust. The catalyst can remove 95% to 100% of NOx emissions.

Interpreting oil analysis data
11/1/2009
Jack Poley
Featured Articles
In September we introduced the notion of spherical evaluation techniques, i.e., approaching the oil analysis evaluation
problem from all directions and nuances possible like, for example, a puzzle.
We started with a significantly out-of-spec viscosity difference in a gearbox with a straight-grade oil, almost always
indicative of a mis-add such as putting the wrong product in the gearbox sump.
Later we presented the same problem with a diesel engine, wherein viscosity decreased substantially, though we
now had to also consider an operating problem, possibly in the fuel-delivery circuit. As a result, this added another layer of thought, which is still a rather simple diagnostic consideration.
The report herein adds yet more complexity to the evaluation process. Note: The data flagged here were flagged
against statistical determinants for similar components and applications.

Shaken, not stirred

Paul Hetherington
Featured Articles
Many years ago I worked for an organization with a medium-sized utility
plant that had four 50-mw, steam-driven turbo-generators operating continuously for about 15 years with the same oil. Over time the oil started to develop a measurable amount of foam in the tanks, to a point where some action was warranted. The oil volume in each of the tanks was a little more than 6,000 liters, and oil changes would have been a fairly significant expense.
Since I am a firm believer in avoiding “quick-fix” additive
treatment products, I chose instead to take a much more systematic and due diligence approach. At least that was the
plan!

Synthetic submarine hydrualic oil
10/1/2009
Dr. Neil Canter
Featured Articles
Lubricant fluids used in submarine propulsion systems must meet very challenging operating conditions. Submarines function very independently, which means their operating systems need to perform reliably over long time periods. If a problem occurs with a submarine at sea, the chances for outside assistance are remote.
A lubricating fluid in a submarine must therefore be very reliable. STLE members
Dr. Richard Sapienza, CEO of METSS Corp., Westerville, Ohio, and William
Ricks, senior research scientist for METSS Corp., say, “Space constraints in a submarine mean that it cannot carry too many materials. Lubricants must not only be reliable but also multifunctional.”

Lean, mean manufactoring machines
10/1/2009
Dr. Robert M. Gresham
Tribology & Lubricants Fundamentals Column, TLT
Through our relationship with the Society of Manufacturing
Engineers (SME), I have come to learn more about a new term called lean manufacturing. What does this
word have to do with tribology and lubrication engineering?
Actually, lean manufacturing has a lot to do with us.
I suppose this subject resonates with me because of my industry experience working in manufacturing for both Du-
Pont and E/M Corp. In those days life was actually pretty easy. All I had to do was ship the right quality at the right cost at the right time. I could put a number on each of these,
and at the end of the day I knew in clear terms whether I had
done the job. Better yet, these numbers were all compared to a standard.

Why superconductivity = super opportunity
9/1/2009
Betty Catalina Kohanloo
Featured Articles
As the flat economy has stressed both industries and consumers
worldwide, almost everyone, it seems, is seeking aggressive
tactics to decrease variable costs stemming from energy
consumption. With economic woes mounting, the energy efficiency concerns
of the 1970s and ’80s are plaguing the
world again.
The rise of resource nationalism in foreign and domestic countries, a
“no drilling in my backyard attitude” by many, increased demands from
developing countries and a stagnant supply has led to escalating energy
prices. Since greater than 63% of all electricity in the U.S. industrial
energy sector is consumed by motors, and due to high electrical costs,
implementing energy-efficient strategies could help reduce unnecessary
spending. By emulating the energy policies of Germany, Japan and others
in the European Union, the U.S. may be able to offset energy costs.

Special Report: Boundary Lubricity Additives
9/1/2009
Dr. Neil Canter
Featured Articles
In a past additive column we explored the different types of extreme pressure
(EP) agents and provided information on future trends to enable readers to
learn more about how to use this important class of additives. We decided on the topic after surveying TLT readers.
Considering the variety of additives used to boost the performance of industrial lubricants, we decided to do another readership survey in mid-2009 to
see what additive type our readers would most like to learn more about. The
majority of readers said lubricity additives have the greatest impact on lubricant performance and is the area they are most interested in learning more about.
From the survey we determined there was some confusion about the differences
between boundary lubricity additives and extreme pressure agents. In this
article, TLT requested interviews with key manufacturers of boundary lubricity
additives to obtain their insights on how these additives function, how to
differentiate the performance of boundary lubricity additives, when to recommend a boundary lubricity additive instead of an EP agent and future trends.

What's the point?

Jack Poley
Featured Articles
We call it “oil analysis” and, as I’ve
often noted, it’s a bit of a misnomer—
actually, more than a bit to me. Following is a short quiz for which (suggested) answers have appeared in previous columns:
The purpose of oil analysis is to:
a. Garner pertinent data
b. Make, preserve or conserve money
c. Extend lube drains with minimal risk
d. Make timely, useful maintenance and
equipment utilization decisions.
The answer is “all the above,” but if one adds the word: “primary” before “purpose,” the answer is (b.) to make or preserve money.

The secret is in the formulation
9/1/2009
Dr. Roger Melley
Featured Articles
Back in the early 1970s I was working with the research department in the chemical division of a multinational
rubber company. In addition to running R&D programs, I provided technical service to our plants around the United
Kingdom. I remember receiving a call from the technical manager of one of our plants in Scotland requesting help
with a particular formulation. It seems that batches mixed on day shift had a tendency to just fail the technical specs, while those mixed overnight were always perfect. They had monitored operations and, as far as they could determine, there were no differences at all in the procedures.

New test method for detecting microbes in MWFs
8/1/2009
Dr. Neil Canter
Featured Articles
Microbial contamination continues to be an ongoing problem in managing
metalworking fluid systems. If left untreated, bacteria and fungi can degrade the components in a metalworking fluid and present health risks to the workers at an end-user facility.
Degradation of metalworking fluids leads to a reduction in fluid performance.
Such detrimental issues as corrosion, increased tool wear and replacement and
increased parts rejection rates also can occur in systems dealing with microbial
contamination. One other factor is the generation of biofilms that can lead to filter plugging.
Determination of the level of microbes is mainly conducted by using dipslides.
STLE-Fellow Dr. Fred Passman of BCA, Inc., in Princeton, N.J., says, “The purpose of the test is to detect microbes by placing a sample of the metalworking fluid in a growth medium for 36 to 48 hours. On one side of the paddle, red spots characteristic
of bacteria can grow while on the other side fuzzy white spots characteristic
of fungi are seen.”

Green redux
8/1/2009
Dr. Robert M. Gresham
Featured Articles
Based on my experiences last fall attending STLE's International Joint Tribology Conference and the Annual Meeting held by the American Oil Chemists
Society, I have waxed a bit about all things green, particularly as they pertain to our industry—probably
more than you ever wanted to read. In these articles I’ve tried to add perspective and make a few key points.
First, green technology has to be financially sound. The global price of crude oil controls these economics. Green
technology has certain inherent costs, as do all technologies, and while we can, through science and engineering, work to reduce these costs, at the end of the day they are what they
are. When the global price of crude is high, exceeding these costs by a respectable margin, these green technologies look pretty good. Conversely, green technologies don’t look so good when the global price is low, as it is at the time of writing
this article. The biggest problem is price swings, which create a moving target.

Test efficacy in oil analysis
7/1/2009
Jack Poley
Featured Articles
In recent columns we’ve addressed the fact that oil analysis is cheaper and implied that overall it was also better. But what does better mean?
Oil analysis consists of a variety of selected tests that reveal accessible information for practical maintenance decisions. Previously, I’ve discussed that most information tested for has remained the same over four decades, but the testing methods changed due to development of increasingly sophisticated
instrumentation. Such development added desirable capabilities and reduced costs.

Upgrading biodegradable lubricant performance
6/1/2009
Dr. Neil Canter
Featured Articles
Interest in the use of biodegradable lubricants continues as more emphasis is
placed on using fluids that are derived from sustainable raw materials. One area
of concern with current biodegradable lubricants is inferior performance compared to synthetic lubricants, particularly from the standpoint of oxidation stability and low-temperature characteristics.
Readily available feedstocks such as soybean oil often do not provide sufficient oxidation stability because of very high levels of polyunsaturated fatty acid chains such as linoleic in the triglyceride structure. These fatty acids are particularly vulnerable to oxidation and, as a consequence, the generation of insoluble varnishes
and residues can occur.

Waste treatment in tough times
6/1/2009
Dr. Robert M. Gresham
Tribology & Lubricants Fundamentals Column, TLT
During tough times it’s important for managers to stay focused and disciplined regarding the things that made their company successful during the good times. This is not to say you don’t embrace positive change or hang on to old
things that aren’t working—those changes should come in good or bad times. Rather, we can get so caught up in trying
to reduce costs and increase sales that we forget the basics.
The management of a company’s waste stream is an example of a behind-the-scenes activity that should not be a major drain on profitability. With proper management waste treatment
can result in such positives as reducing new lubricant purchases, lowering the cost of waste treatment, improving
the environment and eliminating fines and a negative societal
image. You also can generate sales of certain wastes as boiler fuel. In other words, a business case can and should
be made for proper waste management and recycling—even in tough times.

The Mechanism of Copper Corrosion Inhibition by Thiadiazole Derivatives
4/1/1995
Yong-Hong Luo, Bo-Yu Zhong and Jing-Cheng Zhang
Archived Article, Lubrication Engineering (LE)
1,3,4-thiadiazole bisdisulfides inhibit copper corrions by active sulfur in lubricating oils. They react with active sulfur to yield inactive trisulfides as determined by Roman spectroscopy and Mass spectroscopy (MS). The thiadiazole bisdisulfide also reacts to form a protective film on the surface of a copper strip. Surface analytical techniques applied to the copper surface show that an organic film if formed chemically, in which the thiadiaziole ring remains.
