It is used for protection of high-quality steel from corrosion and weathering. The work consists of spraying molten wire on blast cleaned steel. Spraying is carried out by zinc, but zinc is better than the material zinakor = 30% +70% zinc aluminum. On the surface thus treated parts, of aluminum oxides arise from the surface and that protects for long time. component is protected against corrosion Spraying is done on the aluminum heat-stressed products. Melting gas in the spray gun is acetylene and oxygen and compressed air is propellant.
