Metal spraying for coating industrial pieces and products are applied in different industrial fields. In these recent years, many researchers have focused on developing various metal spraying methods and their relevant conditions and characteristics. Metal spaying are applied for revamping and reforming new and worn out pieces. In the surface coating by metal spraying, metal particles shoots to the considered surface to make mechanical coating. The advantages of metal sprayed coating which makes this method more desirable for designers in industrial products are, surface uniformity, good porosity for oil suction, high solidity, adhesion to the base metal, resistance against acids and resistance against impact, rust, pressure and wear. In this paper, an investigation is made on different methods of metal spraying such as hot, cold and plasma spraying methods and in addition to the advantageous and the shortcomings of each one. In addition, the surface preparation for products, are introduced.


Key words: Metal spraying, coating, revamping, mechanical coating.
