Abstract
Ni based materials with solid lubrication of 0%, 10% MoS2, 10% graphite, 5% MoS2+5% graphite at weight fractions were fabricated by a P/M hot press method, respectively. The effects of graphite and MoS2 on tribological properties of Ni based materials were investigated on a pin-on-disk tester. Worn surfaces, microstructures of materials were characterized by scanning electron microscopy(SEM). Results indicate that lubrication effects of MoS2 are superior to that of graphite, and the materials with 10% MoS2 has a low and stable wear rates and friction coefficient.
