Deposition of MoS2 particulate layers by pressure impregnation of porous sliding bearings

With the rapid development of industries and advanced technologies, more and more mechanical devices are required to work at high temperatures. The use of nano- and micro-particle solid lubricants is attracting great attention, particularly for high temperature applications. The structure of the solid lubricant particulate layer together combined with particle functionality determines its performance. The formation of a solid lubricant powder layer with a certain thickness, density and morphology is of great importance to solve the problem of high temperature lubrication. A pressure impregnation/filtering technology is applied for this purpose. The paper describes the phenomena encountered in the pressure filtration operation and defines the parameters of the pressure impregnation technology.
