| Abstract: | The formation of anti-corrosion oxide film on copper were studied. A transparent oxide film was formed on copper after cathodic polariza-tion in a solution consisting of chromate and silicic acid(or silicon dioxide sol).The oxide film is very effective to prevent copper from corrosion.Analysis of XPS indicated that the film is mainly consisted of xCr2O3·ySiO2·zCu. |
