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? 

Society of Tribologists and Lubrication Engineers (STLE), is one of the largest professional societies in the field of tribology and lubrication technology, which serves more than 15,000 industry professionals worldwide.

Our mission is to advance the science of tribology and the practice of lubrication engineering in order to foster innovation, improve the performance of equipment and products, conserve resources and protect the environment.



Online webinars, education courses and professional certification programs offer opportunities for continuing education to enhance your career and create value for your company.




STLE organizes, supports, co-sponsors and hosts meetings to provide the tribology and lubrication communities an opportunity to network, exchange ideas and information.




Educating technical professionals to compete in the global business environment is STLE's core mission of serving as a trusted provider of education and a workforce development partner.



STLE honors its 75th anniversary with a year of celebration. we begin with a salute to our founding fathers - a group of people who embody the spirit of volunteerism.

FEATURED ARTICLE

Bearing the load
(posted on June 14, 2019)
As any kid doing maintenance on her first bike knows, bearings need a lot of grease to keep those wheels turning smoothly. But slopping that gloopy mess in and amongst the ball bearings in the wheel’s hub while catching slight whiffs of petroleum are good reminders that maybe there are more ecologically friendly ways to cut friction. Read more >

MARKET TRENDS
How power-generation systems drive the natural gas engine oils market (posted on June 14, 2019)
Natural gas is a naturally occurring hydrocarbon consisting primarily of methane. It has a wide range of applications and is used both as fuel as well as raw material for manufacturing and industrial applications. As a fuel, it is used to generate electricity, drive vehicles, space heating, air conditioning and cooking, among other uses. As a feedstock, it is used in fertilizer and manufacturing industries. Along with natural gas, methane-containing renewable gases, including biogas and landfill gases, are being harnessed for power generation. Read more >


TECH BEAT
Predicting life of lithium-ion batteries (posted on June 14, 2019)
Under development for some time, lithium-ion batteries have come under scrutiny due to performance deficiencies. One remaining issue is the formation of spiky structures known as dendrites that originate at the battery’s anode. If left unchecked, dendrites will grow until they reach the battery’s cathode, leading to a short circuit that can cause the battery to overheat and potentially catch fire. Read more >
