英文摘要： Solid lubricant coatings are widely used in many high technology fields to solve tribological problems, such as wear, lubrication, adhesion and scuffing of mechanisms encountering extreme environments and severe operating conditions, which would increase the stability and dependability of the mechanisms. Alone with the increasing application of the coatings in oil lubrication conditions, it is exigent to investigate the tribological behaviors of the solid lubricant coatings under oil lubrication. By means of adjusting compatibility and cooperativity between solid lubricant coating and lubricant oil, a new-style solid lubricant coating with long life and good tribological performance is designed and prepared through resin doping, components adjusting and nanoparticles composite technology. The effects of chemical component, microcosmic configuration，prepared technology, and the viscosity and polarity of the oils on the tribological behaviors of the coating under oil lubrication are studied, and the abrasion mechanism of the coating under oil lubrication is discussed. Through this study, the pivotal technique of the coating preparation is acquired, which would provide a frame of reference to the exploitation of coatings with excellent tribological performance and high dependability.
