With this processing, the metal is melted into fine grain and sprayed to the material with the compressed air
to create a membrane and the surface is metalized.
With this processing, the fine-grain grinding material is sprayed to the surface of material at high speed to remove the rust or taint on the surface of material with the shock and "roughen up" the surface of material to improve the adhesion and adherence property of membrane as a preprocessing of metallic surface processing such as plating and thermal spray.
