Composite coating types and uses of metal and composite material

In principle, any person who may plated metal can be used as the metal to prepare composite coatings, but more research and application of only a nickel, cobalt, chromium, copper, zinc, gold, silver, etc., and as the solid particles are mainly two categories, one is to improve the wear resistance of the coating of high hardness, high melting point particles, such as alumina, zirconia, silicon carbide, tungsten carbide, diamond; the other is to provide a self-lubricating properties of solid lubricant particles, such as graphite , molybdenum disulfide, polytetrafluoroethylene, fluorinated graphite and the like. Table 4-29 lists several basic metal and composite material composite coatings and their use.
