Description
先ず、本発明で使用されるアルミニウムは、一般的な構造部材或いは配管部材としてのアルミニウムであり、このアルミニウムを、150℃〜450℃に保持した状態で、高濃度のオゾン含有ガスに接触させることによって、該アルミニウムの表面にオゾンガスによる酸化皮膜の形成(以下単に『オゾン処理』という場合がある)を行う。
(比較例1)
(比較例2)
(比較例3)
その結果、本発明に係るオゾン処理によってアルミの耐腐食性について大幅な改善が認められる。
Claims (5)
- アルミニウム又はアルミニウム合金にオゾンガスを作用させて該アルミニウム又はアルミニウム合金の表面に酸化皮膜を形成するアルミニウムの表面処理方法であって、
