A Molybdenum-Containing Carbon Coating for Tribotechnical Use and Antifriction Properties of Oils under Boundary Lubrication

Аннотация

The results of studies on a monocrystalline carbon coating for tribological uses doped with molybdenum are presented. For comparison, an unalloyed monocrystalline carbon coating, as well as uncoated steel, have been investigated. The studies involved an assessment of the physicomechanical characteristics of the compared materials, as well as of the composition and structure of the coatings, and their influence on the antifriction properties of three model lubricating medias under friction in a boundary lubrication mode. It is established that it is possible to improve the antifriction properties of model lubricating media by applying carbon coatings doped by molybdenum onto the working surfaces of rubbing elements.
