摘要

Solid lubrication refers to the use of solid powder, film or integral material to reduce the friction and wear of the two surfaces of relative motion and protect the surface from damage. A solid lubricating material is a solid powder, film or some monolithic material used to reduce friction and wear between two contact surfaces. In the process of use, through the physical and chemical reaction with the surrounding medium or friction surface to generate solid lubrication film, so as to reduce friction and wear. Solid lubricating materials should have strong adhesion to friction surfaces, low shear strength, good stability (physical thermal stability, chemical thermal stability and aging stability), high bearing capacity, etc. so that effective lubrication can be achieved under harsh conditions to reduce production costs. At present, the most widely used solid lubrication materials mainly include layered lubrication, soft metal, metal oxide, fluoride and oxysalt.
