| 摘 要： | 在机械镀锌、锌-铝工艺的基础上,通过调整活化剂和促进剂的种类及用量,研制开发了机械镀锌-镍合金工艺.利用该工艺在钢基表面上得到了不同配比的锌-镍以及锌-铝-镍合金镀层.对这些镀层进行5%NaCl溶液喷雾加速腐蚀试验以及全浸加速腐蚀试验,并与机械镀锌层进行对比.结果表明,各种配比的锌-镍合金镀层的耐蚀性能皆好于机械镀锌层,并且随着镍含量的增加而提高;锌-铝-镍合金镀层的耐蚀性能比镀锌层提高7倍左右.

| Abstract: | Based on Zinc and Zn-Al alloy mechanical plating, a new Zn-Ni alloy mechanical plating process is developed through adjusting type and dosage of activators and promoters. By using this new process, Zn-Ni and Zn-Al-Ni alloy coatings with different proportions on steel substrate are obtained. Accelerated spray and immersion corrosion tests with 5% NaCl solution are performed on these coatings. The results show that all the Zn-Ni alloy coatings with different proportions are superior to zinc mechanical coating in corrosion resistance, and with the increase of Ni content, the corrosion resistance of the Zn-Al-Ni alloy coating is improved remarkably, 7 times better than that of zinc coating. |
