Abstract
Disclosed is a post-processing method for improving anti-wear and friction-reducing properties of a CrN coating. According to the method, the CrN coating is subjected to a thermal cycling treatment in a temperature range of −20° C. to 60° C. under a humidity environment of 60%-80% R.H. The post-processing method can substantially improve the anti-wear and friction-reducing properties of the CrN coating, so that friction pair parts deposited with the coating achieve a stable operation for a long time.
