Abstract
Description
図1は本発明のAlコーティング方法を説明したフロー図である。
<温度分布の特定方法>
第1のステップでは、ガスタービン翼の冷却通路内面において耐久性と強度信頼性を確保したAlコーティングを実施するべく、冷却通路内面の温度分布を予め特定する。
Alコーティングの耐酸化性に対する効果と、疲労強度への悪影響の程度を把握するべく、耐酸化性と疲労強度の温度依存性を評価し、特定する。
第1のステップにおける「耐酸化性と疲労強度の温度依存性の特定方法」に基づいて図2に示す領域X,Yを規定し、第1のステップにおける「温度分布の特定方法」で特定された温度分布に対して領域Yに相当する範囲を特定して、Alコーティングの施工範囲を設定する。
第2のステップで設定された施工範囲に基づいて、Alコーティングを施工する。
