Wear Behavior of Electrified Copper-MoS2 Powder Metallurgy Materials Under Dry Sliding
Copper alloys without molybdenum disulfide and those containing 10 wt. % and 20 wt. % MoS2 were prepared by means of powder metallurgy. Utilizing an experimental pin-disk apparatus, the tribological behavior of electrified pins fabricated from the various alloy composites was investigated as a result of their interaction with a QCr0.5 bronze disk in motion. The results indicate that the friction coefficient and wear rates of the Cu-MoS2 composites are greatly reduced as compared to the copper alloy alone, material containing MoS2 displayed a relatively constant in friction coefficient for all currents and speeds tested. The frictional coefficients and the wear rates for both the Cu-10% MoS2 and Cu-20% MoS2 alloy composites are very similar for each current and speed tested.
