Self‐Lubricating W–S–C Nanocomposite Coatings

This paper is aimed on a perspective low‐friction coatings, the W–S–C system deposited by magnetron sputtering, which exhibits extremely low‐friction coefficient together with high‐load‐bearing capacity. Special attention has been paid to the analysis of the frictional and wear mechanisms under different operating conditions, such as the contact pressure, the air humidity, and the temperature. The formation of a thin self‐lubricating WS2 tribolayer, which was observed regardless on the sliding conditions, is the driving force for the promising frictional properties of the coatings. magnified image
