The article "Development of PPESK high temperature resistant self-lubricating wear-resistant coating" introduces the preparation of a wear-resistant coating with high temperature resistance and self-lubricating properties using PPESK as the base material and adding appropriate amount of polytetrafluoroethylene and silicon carbide as fillers. Specific process. The effects of different additives and loads on the wear loss were studied. And use tinplate, muffle furnace, Taber 5155 wear-resistant testing machine, etc. to test the conventional performance, high temperature resistance, medium resistance, wear resistance, etc. of the new coating.
The results show that the wear loss mass of PPESK wear-resistant coating is 0. 012 1 g when the load is 1 250 N and 10000 r/min, the friction coefficient is Us = 0. 196, Ud = 0. 146, and the pencil hardness is greater than 5H, which is a An industrial wear-resistant coating with excellent performance.
