Doping Diamond-Like Carbon Coatings on Rubbing Parts as a Method for Improving Antifriction Properties of Lubricants

The potentialities of improving the antifriction and antiwear properties of lubricants under friction in a boundary lubrication mode by means of doping carbon coatings on the contacting parts of lubricated friction units with the use of different elements of the Periodic Table are considered. The results of studies on the tribotechnical characteristics of such coatings have shown the fact that doping carbon coatings with tungsten, molybdenum, titanium, and silicon in a number of model lubricants is quite efficient.
