Description
まず、比表面積を増大させるため、20%沸騰塩酸に試験片を浸漬し、20分間のエッチング処理を行う。これを、純水で塩酸の掛け流し洗いを行い、乾燥器にて60℃で水分を蒸発させる。
白金族元素コーティング液として、1mol/Lの塩化白金イリジウム酸を含有する溶液を用いた以外は実施例1と同様にして金属酸化物層を形成した。なお、白金とイリジウムの比率は2:1とした。
まず、比表面積を増大させるため、20%沸騰塩酸に試験片を浸漬し、20分間のエッチング処理を行う。これを、純水で塩酸の掛け流し洗いを行い、乾燥器にて60℃で水分を蒸発させる。
容量900mlの静置式オートクレーブに水を約500ml入れて、実施例1、2及び比較例1並びに未処理試験片(標準品)を水中に浸漬させた。脱気後に温度約360℃、圧力18.7MPaに昇温昇圧した。試験の前後にて腐食重量増を測定した。
