What is tribology?
Tribology is the study of science and engineering of interacting surfaces in relative motion. It includes the study and application of the principles of friction, lubrication and wear. Tribology is a branch of mechanical engineering and materials science.

Tribology’s economic and commercial impact is vast. The science reduces energy use, lowers the cost of maintenance and replacement, develops new technology, and solves resource problems, such as the lack of clean water. Proper tribological procedures save an estimated 1.3% to 1.6% of a nation’s gross domestic product—a savings of hundreds of billions of dollars (U.S. currency) in larger countries. Virtually every nation has realized it cannot afford to overlook the economic, industrial, and commercial advantages of tribology. Consequently, tribology is a science that is constantly being advanced by thousands of researchers around the world. Lubrication engineering is the practical application of that science, generally in the development of lubricants and their proper usage and maintenance. 

What is STLE? 

STLE, one of the largest professional societies in the field, serves 15,000 industry professionals worldwide.

Passenger car engine oil change intervals: Past, present and future 
(posted on November 19, 2018)
The growing performance demands placed on today’s passenger car engine oils have led to the use of lower-viscosity lubricants needed to meet more demanding fuel economy requirements. But these lower-viscosity engine oils also raise concerns about the potential for increasing engine wear.

LUBRICATION FUNDAMENTALS
I know I'm getting a little rusty (posted on November 19, 2018)
Interestingly, from the time of the Iron Age the whole subject of rust and corrosion has been a troublesome topic. The early Greeks noticed that metallic things degraded in the sea faster than in fresh water. For centuries people observed corrosion but really didn’t know much about it, didn’t understand it and didn’t know how to control it. They just kind of lived with it. Read More >

Foam generation in oil-based lubricants: Evaporation 
(posted on November 19, 2018)
Foam continues to be a problem that formulators and end-users of lubricants must overcome. Air is an inferior lubricant, and its excessive presence due to foam is harmful in lubricant systems. The presence of foam can cause operational difficulties such as reducing lubricity, preventing heat removal and increasing wear. Read More >
