Abstract:

The hardness of the substrate metal affects the performance of MoS2 as a solid lubricant in two ways. Soft metal substrates facilitate adhesion and harder substrates facilitate cohesion. An effective compromise between these conflicting factors is achieved by pre-coating a hard substrate with a thin film of a softer metal Pb, Au, Ag, etc.. Soft metal coatings are synergistic with MoS2 and enhance its performance as a solid lubricant. Measurements of the rates of wear of different metals lubricated by MoS2 show that the most important factor in the wear process is abrasion by the MoS2 itself. Author
