Abstract At present，galvanizing is still the main anticorrosion technology for steel and iron products.The mechanism,technical process and the characteristics of hotdip galvanization,mechanical plating and electroplating with zinc are introduced.In recent years, because environmental protection laws and regulations have been strengthening，the application of technological process of traditional electroplating and hotdip galvanizing has been limited in many countries due to pollution problem.Thus, the surface treatment of steel and iron parts is facing an revolution for low energy consumption, low pollution，high efficiency, high quality and green procese.The mechanical plating is one of the clean surface treatments，which is extended and popularized vigorously, in the world and in China,becoming one of the common hardware surface treatments gradually.
