Increasing Wear Resistance of Copper Friction Pair with Electrically-Conductive Tribological Cu-Mo-S Coatings

摘要

The composite solid lubricant Cu-Mo-S coating was produced by pulse magnetron sputtering system. The electrical resistivity of deposited Cu-Mo-S coatings was (22.8±3)x 10~(-8) Ohmxm. Cu-Mo-S coatings decrease the wear rate of the copper friction pair by 38 times. The decrease in the wear rate occurs owing to the formation of a transferred film on the counterface.
