Abstract The influences of MoS2 and graphite on the tribological properties of Ni--Cr based self--lubricating composites prepared by powder metallurgy were investigated. The results show that the micro--hardness of composites decreases obviously with the increase of content of MoS2. While the friction coefficient and wear rate of the composites don’t change evidently with increasing the content of MoS2 from 10% to 15% (mass fraction). The micro--hardness of composites reduces gradually with the rise of graphite amount, the friction coefficient of composites increases slightly at 400℃and 800℃. When the content of graphite is 10%, the friction coefficient of composite is lowest at room temperature. Addition of 5% MoS2 and 10% graphite, the friction coefficient of composites keeps 0.48--0.65 meaning the synergic lubricating effect between graphite and MoS2, and the wear rate is an order of magnitude higher than that of composites containing MoS2 alone or graphite alone.
