DEFECT REPAIR METHOD FOR HIGH TEMPERATURE COMPONENT, HIGH TEMPERATURE COMPONENT, AND REPAIR MATERIAL CHARGING APPARATUS

摘要

<P>PROBLEM TO BE SOLVED: To secure a repaired part in a high temperature strength equal to a portion unnecessary for repairing or to a repairing material without causing any deformation due to repair. Ž<P>SOLUTION: The defect repair method for the high temperature component, which repaires a defective fracture 21 caused in a stationary blade 11 of a gas turbine to be operated under a high temperature condition, includes: a charging process (Fig.2(C)) for charging a blazing repair material 20 into the defect 21; and a blazing process (Fig.2(D)) for blazing the fracture defect 21 by a diffusion heat process using a blazing repair material 20. In the charging process, when the blazing repair material 20 is charged in the defect 21, the stationary blade 11 is vibrated to charge the blazing repair material 20 in the defect 21.
