Title
Research Papers / Environment : Effects of Sn and Al on the High Temperature Oxidation of 6 : 4 Brass
문재진Jae Jin Moon,이동복Dong Bok Lee
Abstract
Four different brasses i.e., Cu-39.49%Zn (6:4 brass), Cu-39.11%Zn-0.80%Sn, Cu-38.85%Zn-0.45%Sn-0.47%Al, and Cu-37.68%Zn-0.46%Sn-1.82%Al were oxidized in air at 873, 973, and 1043 K to investigate the effects of Sn and Al on the oxidation behavior of 6:4 brass. The oxidation resistance of 6:4 brass increased with the addition of Sn and Al, The good oxidation resistance obtained in Cu-37.68%Zn-0.46%Sn-1.82%oAl was mainly attributed to the formation of Al_2CuO_4 that formed in the ZnO-rich oxide scale.
