摘要
通过对双氧水稳定剂的研究 ,开发了铜及其合金H2 O2 BTA稳定钝化处理新工艺 ,替代铜合金的铬化处理工艺。处理后黄铜的出光性和耐蚀性均有明显提高 ,可以避免铬化处理对环境的污染。电化学极化曲线研究表明 ,该方法在铜表面上能产生良好的钝化保护膜 ,对铜电极的阴极和阳极的腐蚀电化学过程均有抑制作用。
The H 2O 2 stabllizer was adopted to the no chromium passive treatment of brass surface by H 2O 2 benzotriazloe processing. The use of H 2O 2 stabllizer enhanced the protection effect of passive film on brass surface. Electrochemical polarization curve study showed that the new treatment suppressed both the anodic and the corrosion cathodic reaction.
