The effect of the ultradispersed diamond phase upon the tribological behavior of coatings based on galvanic chrome

摘要

The effect of addition of ultradispersed diamond upon the behavior of electrolytic chrome-based coatings has been investigated. It has been established that the surface morphology, microhardness, parameters of wear and scoring resistance after such addition improve compared with the corresponding parameters of the basic coating. In particular, the mass wear of modified coatings in friction without and with lubrication reduces 1.5 to 3 times, the friction coefficient by 10 to 20%.
