It was found that Zr(IV)-Cr(III) or Ti(IV)-Cr(III) composite oxide film is formed on a stainless steel by cathodic polarization in a chromate solution containing Zr(IV) or Ti(IV) ions. The method provided good oxidation resistance to SUS 430 stainless steel at elevated temperatures. In principle, it is possible to develop other composite oxides including Y(III), Ce(IV), La(III), Gd(III), and others. The present method is similar to commonly used electrolytic chromate treatment, and it has potential advantages for practical applications.
