者の接着状態はいわゆる機械的接着である。The conventional metal spraying method is a method in which the surface of a base material is roughened by sandblasting, shot blasting, etc., and then metal spraying is performed thereon to form a metal coating. In other words, in the conventional metal spraying method, the base material and the sprayed metal are bonded to each other by interlocking with each other due to the irregularities on the surface of the base material, and the state of adhesion between the two is so-called mechanical adhesion.

ある。As explained above, according to the present invention, since the thermal sprayed metal coating is bonded to the surface of the base material via an adhesive, the adhesive strength between the base material and the thermal sprayed metal coating is strong, and the thermal sprayed metal coating is resistant to expansion due to impact or temperature changes.
Even after repeated shrinkage, the sprayed metal coating does not crack or peel, which has a significant effect on improving reliability.
