Effects of copper-coated MoS₂ on friction performance of bronze-graphite-MoS₂ self-lubricating materials

Abstract

Two kinds of bronze-graphite-MoS₂ self-lubricating materials with copper-coated MoS₂ and uncoated MoS₂ were prepared by powder metallurgy. Friction and wear experiments were carried out under 4 N and 10 N loads respectively, and the effects of copper-coated MoS₂ on the friction performances of the materials were studied. Results showed that the way of copper-coated on the surface of MoS₂ could reinforce the bonding between MoS₂ and matrix, and inhibited the formation of MoO₂. Moreover, both materials formed a MoS₂ lubricating film on the surface during the friction process. While the lubricating film formed after copper coating on MoS₂ was thicker and had uneven morphology, it was more conducive to improving the friction performance of the material. Compared with conventional materials, the wear rate of copper-coated materials was reduced by one order of magnitude, and the friction coefficient was also reduced by 22.44% and 22.53%, respectively, when sliding under 4 N and 10 N loads. It shows that copper-coated MoS₂ can improve friction properties of bronze-graphite-MoS₂ self-lubricating materials furtherly.
