摘　　要：检验酸性镀锌军绿色钝化膜层质量的重要指标是耐蚀性和结合力,为提高耐蚀性和结合力,结合生产实际,研究出了一种酸性镀锌低铬军绿色钝化工艺。详细介绍工艺的流程、钝化与封闭的方法,按照美国材料试验协会检验标准进行检测,结果表明:该工艺满足汽车挡盖质量要求。In order to improve the corrosion resistance and binding force, a kind of green passivation process for zinc plating with acid potassium salt and low Chromium has been developed. The process, passivation and sealing methods of the process are introduced in detail. According to the test standards of the American Materials Testing Association, the results show that the technology meets the requirements of the vehicle cover quality.
