摘要： PROBLEM TO BE SOLVED: To provide a masking member which reduces the peeling of a coating film associated with the removal of the member, even without increasing a burden of working. SOLUTION: The film-forming method includes: preparing first and second masking members 2 and 3; and making an inner circumferential surface 6a of a hole of the second masking member 3 project in a direction closer to a region side on which a thermal-sprayed layer 8 is formed than an inner circumferential surface 5a of a hole of the first masking member 2. Then, the inner circumferential parts of the holes of the first and second masking members 2 and 3 form a substantial undercut shape, even without applying special working such as undercut working to the first and second masking members 2 and 3. Thereby, the method reduces the deposition of the thermal-sprayed layer 8 on the respective inner circumferential surfaces 5a and 6a of the holes of the first and second masking members 2 and 3, when the thermal-sprayed layer 8 is formed, and can suppress the peeling of the coating film when the masking members (the first and second masking members) are removed after the coating film has been formed.

摘要： PROBLEM TO BE SOLVED: To provide a thermal spraying pretreatment method for a casting which can make the surface of a casting into preferable surface conditions from the viewpoint of securing the adhesion force of a sprayed coating.
SOLUTION: Before shot blast treatment, a casting surface 1s is subjected to shot peening treatment using spherical shot peening materials 2, compressive residual stress is applied to the surface part of the casting 1, and the surface part is made into a surface hardened layer 3. Even when a cavity 4a is present at the part directly below the casting surface 1s, a blast material is not deeply infiltrated into the casting surface part, and the new appearance of the cavity 4a is prevented. On the other hand, regarding the reduction of the rough state of the casting surface 1s, the degree in the reduction of the surface conditions is compensated with the increase of the surface hardness. Further, in the case a cavity 4b appears on the casting surface 1s, the shot peening materials are infiltrated into the cavity, and, not only the parting of a sprayed coating can be prevented, but also, upon shot blast treatment, grinding of the peripheral part in the cavity 4b is suppressed, and the expansion of the cavity (size) can be suppressed.

摘要翻译：要解决的问题：为了提供一种用于铸造的热喷涂预处理方法，其可以从确保喷涂涂层的附着力的角度考虑，从而使铸件的表面成为优选的表面状态。解决方案：在喷丸处理之前，使用球形喷丸硬化材料2对铸造表面1进行喷丸硬化处理，对铸件1的表面部分施加压缩残余应力，并将表面部分制成表面即使在铸造面1s正下方的部分存在空腔4a时，也不会将喷砂材料深深地渗透到铸造面部，并且防止了空腔4a的新外观。另一方面，关于铸造表面1s的粗糙状态的降低，表面状态的降低程度由表面硬度的增加来补偿。此外，在铸型表面1s上出现空腔4b的情况下，喷丸硬化材料渗透到空腔中，不仅可以防止喷涂的分离，而且可以在喷丸处理时，空腔4b中的周边部分被抑制，并且可以抑制空腔的膨胀（尺寸）。版权所有（C）2009，JPO＆INPIT
