摘要： PROBLEM TO BE SOLVED: To carry out coating removal by acid pickling by releasing residual stress while preventing stress corrosion cracking and deterioration in the strength/ductility of a base material.
SOLUTION: A moving blade 1 formed of γ' phase precipitation strengthened Ni-base alloy has an oxidation-resistant coating on the surface. In order to carry out recoating, heating is performed at 975 to 1,050°C in an annealing furnace 2 to make both Cr
23 C
6 type carbides and (Ti, Nb)C type carbides enter into solid solution and reduce the amount of these carbides present and then heating is performed at 1,050 to 1,250°C at which residual stress can be relieved and initial melting does not occur to relieve the residual stress. Because the coating is removed by carrying out acid pickling using hydrochloric acid 4 in a state where the carbides are eliminated and the residual stress is relieved, the occurrence of stress corrosion cracking can be prevented.
