摘要： PROBLEM TO BE SOLVED: To reduce a residual tensile stress of sprayed coating film and to improve the adhesion of a coating film to a substrate, into a thermal spraying material, by incorporating substance volumetrically expanding when the thermal spraying material is thermally sprayed on the substrate and cooled. SOLUTION: At the time of forming a sprayed coating film of metal or alloy, a thermal spraying materials is incorporated with substance volumetrically expanding when the thermal spraying material thermally sprayed in a substrate is cooled, and the thermal spraying material is thermally sprayed. In this method, as the volumetrically expanding substance, the one such as steel series transformed into martensite at the time of cooling after the thermal spaying is adopted. In this way, it is considered that, since the heat of the sprayed coating 2 on the side approximate to the part of the substrate in the sprayed coating 2 escapes to the substrate more easily, in an ordinary form, martensitic transformation is promoted on the side of the boundary face between the sprayed coating 2 and the substrate more easily than the case of the surface side of the sprayed coating 2. Thus, the volumetric expansion in the boundary region between the sprayed coating 2 and the substrate can be expected, and the adhesion in the boundary region can be improved.
