摘　　要：通过对CuZnAl合金在3.5%NaCl和3.5%NaCI+NH3溶液中的腐蚀速率和电化学参数的测试及CuZnAl合金腐蚀形貌的观察,分析了NH3对CuZnAl合金在3.5%NaCl溶液中腐蚀行为的影响。结果表明:NH3能改变CuZnAl合金的腐蚀形貌,使合金的腐蚀电位负移,腐蚀电流增加,合金的腐蚀速率增大。Through the measurements of the average corrosion rate and electmchemlcal parameters of CuZnAl alloy in 3.5%NaCl and 3.5%NaCl ＋ NH3 solutions and the observation of the corrosion morphology of the alloy, the corroding behavior of NH3 on the alloy is analyzed. The results show that the addition of NH3 in 3.5 % NaCl solution can change the morphology tentiality move toward the negative direction so that the corrosion of corrosion and make the corrosion powill be accelerated
