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.
