…When conditions that destroy this scale are applied or when dissolving substances are present, abnormal oxidation occurs, which becomes a problem in high temperature corrosion. When metals deform under stress, the surface film is destroyed, but if the rate at which the corrosion reaction begins at the break exceeds the rate at which it can be repaired, it develops into localized corrosion. The combination of wet corrosion conditions and mechanical destruction of the film can cause severe localized damage such as corrosion fatigue, impact corrosion, and stress corrosion cracking. … *Some of the terminology that refers to "localized corrosion" is listed below.

…このスケールを破壊する条件が加わったり,溶解する物質が存在するときに起こる異常酸化が高温腐食high temperature corrosionでの問題となる。応力の存在下で金属の変形が起こると表面皮膜の破壊が起こるが,破れ目を起点とする腐食反応の進行の速度がそれを補修する速度を上回ると局部腐食に発展する。湿食条件と機械的な皮膜の破壊とが重なり合うと腐食疲労,衝撃腐食,応力腐食割れなどの過酷な局部損傷の原因となる。… ※「局部腐食」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
