%X The corrosion rate, corrosive wear rate and polarization curves of aluminium brass and cupronickel alloy were determined in 3.5%NaCl and 3.5%NaCl NH3(NH4 )solutions, the wear tracks of copper alloys were observed by SEM, the specific energy of the surface layer after corrosion was also measured by single pendulum scratching test. Experimental results show that the addition of ammonia or ammonium in 3.5%NaCl solution can accelerate the corrosion and corrosive wear of copper alloys, the corrosion potential shifts negativly,the corrosion current density increases. The ammonia or ammonium caused the surface embrittlement of copper alloys during corrosive wear.
