Thorough oil analysis
Jeanna Van Rensselar, Senior Feature Writer | TLT Feature February 2019
There is a tendency to focus on one aspect of an oil analysis report and ignore everything else. Examples include looking only at the most recent sample, only trending one test, etc. By not looking at the sample results thoroughly, the results can become meaningless or even detrimental to determining the root cause of a machinery problem. By missing one piece of the puzzle, technicians end up working in the wrong direction—wasting time and money.

Electricity generated from salt water and superhydrophopic surface
Dr. Neil Canter, Contributing Editor | TLT Tech Beat February 2019
One resource readily available to researchers is salt water. Utilization of salt water for commercial purposes has proven difficult. An example is the large amount of energy needed to desalinate salt water to produce fresh water, which is in short supply. Read Full Article

Thermal Conductivity and Flash Temperature
By Tom Reddyhoff, Aaron Schmidt, & Hugh Spikes
The thermal conductivity is a key property in determining the friction-induced temperature rise on the surface of sliding components. In this study, a Frequency Domain Thermoreflectance (FDTR) method is used to measure the thermal conductivity of a range of tribological materials (AISI 52100 bearing steel, silicon nitride, sapphire, tungsten carbide and zirconia). The FDTR technique is validated by comparing measurements of pure germanium and silicon with well-known values, showing discrepancies of less than 3%. For most of the tribological materials studied, the thermal conductivity values measured are reasonably consistent with values found in the literature. However the measured thermal conductivity of AISI 52100 steel (21 W/mK) is less than half the value cited in the literature (46 W/mK). Further bulk thermal conductivity measurements show that this discrepancy arises from a reduction in thermal conductivity of AISI 52100 due to through-hardening.

2019 Keynote Address will explore Racing into the Future – Impact of Tribology on Vehicle Electrification
Electric mobility is quickly moving from someday to today as electric cars are becoming common, and even electric scooters and bikes are entering the mobility scene. The benefits of electrification are many, including reduced emissions and maintenance, and improved performance. It is also unsettling to many engineers who have spent a career enabling conventional engines and transmissions. While the needs of electric powertrains are different, the fundamentals are the same. We have been learning about those needs on the racetrack, through Formula E, as well as in conventional automotive powertrains. This talk will share some of these lessons and point the way of future tribology efforts.
The 2019 keynote address will be presented by Jeff Hemphill, Chief Technical Officer, Americas, with Schaeffler Group USA Inc. Join Jeff and STLE we explore the future of electric vehicles.
