Abstract (en)

A to-be-repaired damaged part, which occurs in a rotor (1), is removed and shaped by machining or grinding (S1). The shaped surface, from which the to-be-repaired damaged part is removed in the step (S1), is roughened by a blasting process (S2). A coating is formed on the surface, which is roughened in the step (S2), by a high-velocity flame spray apparatus (S3). The coating, which is formed in the step (S3), is finished by machining or polishing (S4). A defect inspection is performed to check presence/absence of a defect (S5). A dimensional/guality inspection is performed for the part repaired (S6) in the step (S5).
