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

Using computer modeling to prevent polymer surface damage
(posted on May 17, 2019)
Polymers are comprised of molecules that have long, repeating chains. Their properties depend on the type of molecules that are bonded and how they are bonded. The range of polymers and properties is enormous. For example, some polymers, like rubber and fabric, are flexible and others, like epoxy, can be inflexible. Read more >

LUBRICATION FUNDAMENTALS
Change is still a good thing! (posted on May 17, 2019)
Last month I wrote on some of the changes I had seen in our society since joining as a member in 1981 and later serving as part of the staff. I was mostly concerned with the changes resulting from our efforts to become an international organization. As a consequence of some of those changes, we also became a better society for our individual industrial members and our corporate members. Read more >

Direct borohydride fuel cells (posted on May 17, 2019)
In a previous TLT article (1), the challenge in improving the effectiveness of a solid oxide fuel cell involves improving the lanthanide, strontium, cobalt and iron cathode that is widely used to reduce oxygen. The efficacy of the cathode is hindered due to strontium segregation migration. Researchers improved the performance by applying a multiphase coating on the cathode, which reduced strontium migration and improved cathode performance and durability.  Read more >

PRESIDENT'S REPORT 
My 2018 - 2019 STLE Presidency (posted on May 17, 2019)
It has been my honor to be your president for the last year. It is a tribute to the entire membership that I had such a nice time visiting our partner events, local section meetings and industry meetings. A tribute because this society is very well liked and respected around the world. People respect STLE because of our size, ability to make a difference, our huge volunteer movement and our ability to give back to the society. Read more >
