に食い込ませることも行っていた。[Conventional technology] Conventionally, in order to improve corrosion resistance and wear resistance by coating the surface of metal, etc. with ceramics, ceramic particles were sprayed at high speed from a nozzle toward the metal surface. They used so-called thermal spraying to form a ceramic film by biting into the metal. Alternatively, at this time, the ceramic particles were heated in advance to a molten state so that the ceramic particles would bite into them more firmly.

A layer is formed.

In this case, the adhesion of the coating layer to the base material l and the physical properties of the coating layer can be arbitrarily changed by changing the content of the particles 4 and 5 of the kneaded material in each layer of the coating layer 2. A strong composite coating layer can be formed by using different types of materials for each coating layer, or a composite coating layer having different physical properties can be formed by combining the two coating layers. Further, the irradiation with the laser beam 3 may be performed every time one layer is coated, or every several layers, or after all layers are coated.
