Research on the Mixing way and Content of Molybdenum Disulfide with Copper Matrix Self-Lubricating Composites
The new type of copper matrix self-lubricating composites were prepared by powder metallurgy route. The influences of milling way and content of molybdenum disulfide on composites’ microstructure and tribological properties were researched. It is found that, MoS2 can’t participate in the process of mechanical alloying together with graphite and copper powder. When the mass fraction of MoS2 increases from 0% to 10%, the coefficient of friction of composites MoS2-G-Cu reduces correspondingly, however the three-dimensional network structure of copper matrix was damaged seriously in sample 10% MoS2-G-Cu .After the wear text there will come out solid self-lubricating film on the surface of sample 5% MoS2-G-Cu and 10% MoS2-G-Cu .
