Research on Anti-Friction Mechanism of Ni60A/MoS2 Composite Coating
Based on the research of the tribological properties of the Ni60A/MoS2 composite coating, this paper has studied and discussed the self-lubricating effect and mechanism of the MoS2 film in the Ni60A /MoS2 composite coating. Research shows that when self-lubricate coating rub, MoS2 solid lubricant can be precipitated, forming lubricating film on the friction surface through dragging. The Solid lubricate film of MoS2 is an important factor that lead the friction coefficient of Ni60A/MoS2 composite lubricate coating decrease. Meanwhile we analyze the formation phenomenon and friction and wear properties of self-lubricate coating, which show forming mechanism of the lubricating film contain four stages, that is, the friction beginning stage, MoS2 precipitating stage, MoS2 covering stage and MoS2 forming stage.
