Research on Lubrication and Wear-Resistant Mechanism of Ni60A/MoS₂ Composite Coating

Abstract:

The influence of MoS₂ lubrication phase on the tribological properties of the Ni₆₀A/MoS₂ composite coating was conducted on UMT-2 micro-wear testing machine (USA), discussing the self-lubricating effect and mechanism. The result shows that with the increasing content of MoS₂, the friction coefficient of the coating which changed with the increasing content of the MoS₂ presents firstly decreases then increases, and the value reach the minimum when the quality percent of MoS₂ wrapped with Nickel is 35%. Low-friction property of the Ni₆₀A/MoS₂ composite coating is due to the forming of MoS₂ lubricating film in friction surface. The decreasing of the friction coefficient of the coating is in proportion to the coverage area of MoS₂ lubricating film.
