Selection of copper sulfate and nitrate for passivator to regulate the content of chromic anhydride,the plating layer and treatment,to be black passivation film binding, and color uniformity,in 5%NaCl neutral salt spray corrosion test,chemical spray coating in a row after 32h corrosion began to appear now,and the plating layer in the 96h after the dot,black passivation layer in the 800h,the absence of any corrosion,corrosion resistance coating compared to a single very markedly improved.
3.选用硫酸铜和硝酸盐为钝化剂,调节铬酐的含量,对电镀层黑化处理,得到的黑色钝化膜结合力好,色泽均匀,在5%NaCl的中性盐雾腐蚀实验,化学镀层的在连续喷雾32h后开始出现腐蚀现在,而电镀层在96h后出现斑点,黑色钝化层在800h内,无任何腐蚀现象,耐蚀性单一镀层相比有非常明显提高。
