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.

摘要： PROBLEM TO BE SOLVED: To provide a film formation method to a grooved part which decreases the excess projecting parts of the film after forming and lessens the burden of post-working in the case the film is formed by thermal spraying in the grooved part. SOLUTION: As a stage for working a pregrooved shape 4 to the part to be formed as the grooved part 2 of a base material 3, a pregrooved shape 4 is formed by machining, casting, etc., on the flat surface of the base material (or the surface of a test base material) prior to the working of the pregrooved shape by a separate stage so as to have a slope 4a which is reverse from the deposition shape of a virtually or empirically formed test film and flares to a projecting shape toward its aperture. The thermally sprayed film 1 is formed by using a thermal spraying gun in the formed pregrooved shape 4.

CONSTITUTION: This Al alloy surface-treated member has a surface layer part of an Al alloy contg. an intermetallic compd. dispersed by 20-60% by area and an anodically oxidized layer formed by anodically oxidizing the surface of the surface layer part. The toughness of the anodically oxidized layer itself is low, but since a finely divided structure is imparted to the layer by the presence of the intermetallic compd., the toughness is improved and cracking can be suppressed.
