Zirconium alloy is used as fuel lod in unclear plant. It is a corrosion-resistant alloy. But wear property of zirconium alloy isn't investigated enough in dynamic corrosive environment. In this work, therefore, wear test of zirconium alloy was carried out and corrosive wear property was investigated with changing load and anode/cathode area ratio. Wear test of zirconium alloy, sliding against alumina, was carried out in pure water and Na_2SO_4 solution. Potential drop, ΔE, of zirconium alloy during wear test increased with load and wear volume was proportional to load. Then electrochemical wear was about 15%, and the mechanical wear was predominant in this case. Electrochemical wear increased as area ratio decreased.
