Abstract
【解決手段】 本補修した部品は、約1〜3milの厚さのその一部分とオーバレイボンディングコートとが除去されて厚さが減少した残余ベース金属基体を形成したベース金属基体を有するエンジン運転使用済み部品を含む。本補修した部品はさらに、残余ベース金属基体に施工された約10〜60原子%のアルミニウム含有量を有する合金を含む低成長耐環境性ボンド皮膜を含み、基体内への耐環境性ボンド皮膜の成長が以前のボンディングコートよりも小さいので次の部品補修時に約1〜3milよりも小さい厚さの残余ベース金属基体が除去されるようになる。本補修した部品は、延長した部品寿命と増大した補修性とを有する利点がある。
