The Friction and Wear international journal is a competent information source on science researches in the field of friction, wear, lubrication, and their practical applications. It has been edited by The Metal-Polymeric Systems Mechanics Institute named after V.A. Bely of the National Academy of Sciences of Belarus.
In the latest issue of the journal, the ‘Efficiency of Anti-Friction Solid-Film Coatings Application for Metal-to-Polymer Friction Pairs’ article has been published.
The tests results described in this article prove that use of anti-friction solid-film coatings based on molybdenum disulfide and polytetrafluorethylene enables to reduce linear wear of the samples by 5.1 to 8.9 times, and friction coefficient – by 1.2 to 2.2 time.
At the present time, a lot of machinery units are designed using polymer constructive materials that interact with metal parts in process of friction.
Reducing friction and wear of such units including by using anti-friction solid-film coatings is one of the promising tasks of the up-to-date industry.
Use of anti-friction solid-film coatings for the globe elements parts interacting in pair with plastic liners, in particular, is of practical interest.
As studies show, use of anti-friction coatings effectively manages with the tasks on extending service lifetime of metal-to-polymer friction pairs even without using greases. By means of selecting optimal combination of anti-friction solid-film coatings and greases, it is possible to reach reduction of linear wear of the counter parts down to 14.2 times, and friction coefficient – down to 4.4 times.
