To prevent corrosion, wear or fatigue fracture of steel during storage, transport and use, surface coating treatments are widely applied, including surface diffusion of Zn, Al, Cr, V, Nb and B. Coating processes include hot dipping, electroplating, electroless plating and thermal diffusion. Coatings and platings not only improve the appearance of components and repair surface defects, but also give the surface special properties, including higher surface hardness, wear resistance, corrosion resistance, electrical conductivity and high-temperature oxidation resistance. Products involved include household appliances, automobiles, doors and windows, metal fasteners and electronic products.
