In order to develop oxygen sensor using oxide scales formed on the surface of zirconium alloy, we focused on zirconium and copper alloy system. It was expected that the oxide scale of Zr oxide on the alloy is thin and elaborate compared with that on the pure Zr because the activity of Zr in the alloy is reduced and the oxidation rate of alloy become slow. Therefore the oxidation behavior and mechanism of two phase alloy, Zr-35Cu which is composed of ZrCu and ZrCu, was studied. The results showed the oxidation rate of the alloy was same with that of the pure Zr.
