镀锌层三价铬彩色钝化工艺研究

Study on Three Price Chromium Colored Passivation Technology of Zinc-plated Layer

在实验的基础上提出了一种镀锌层三价铬彩色钝化的工艺,研究表明,镀锌层经过钝化处埋后,其耐蚀性接近铬酸钝化的结果,但对环境的污染大大降低,有较高的实用价值。

This text has put forward a kind of zinc-plated technology of layer of three price chromium colored passivation on the basis of experiment. Research shows that after the passivation is dealt with, corrosion resistance of zinc-plated layer is close the result of the sour passivation of chromium. But the pollution to the environment is reduced greatly , there is higher practical value.
