【摘要】 通过失重悬挂法和中性盐雾等腐蚀试验 ,研究了多种添加剂对铜及其合金的缓蚀作用。结果表明 :在BTA溶液中加入一定量的有机羧酸和稀土RE(IV)盐后 ,由于三者的协同效应 ,显著提高了钝化膜的性能更多还原

【Abstract】 Weight loss and salt spraying test were applied to study the inhibition of copper and copper alloy. The results show that when BTA was compounded with race earth and organic acid , the synergistic effect was excellent and passivating films were futher improved in antitarnishing.更多还原
