| Abstract |
Brass(60%Cu-40%Zn), brass-0.83%Cr, brass-0.81%Zr and brass-0.80%Sn alloys were prepared by induction melting followed by thermomechanical treatment. Oxidation tests were performed on the prepared alloys between 600 and 770℃ for up to 1320hr in air. It was found that the oxidation resistance increased in the order of brass, brass-0.81%Zr, brass-0.83%Cr and brass-0.80%Sn. The oxide layers formed on all the prepared specimens were primarily comported of ZnO. Throughout the existing ZnO layer, Cu-oxides in ease of brass, and (Cu-oxides + Sn-oxides) in case of brass-0.80%Sn were additionally present. ZrO₂ in case of brass-0.81%Zr, and CuCr₂O₄ in case of brass-0.83%Cr were found at the bottom part of the ZnO layer. |
