铝合金的表面保护层

Corrosion-resistant Layers for Aluminum Alloys

传统的用铬酸盐对铝合金进行表面抗蚀处理存在铬污染问题,有许多研究工作在努力开发代铬无毒或低毒的表面保护层,其中有化学方法,也有物理方法,本文中对有关研究工作做了概述.

Research is currently under way to find alternatives for chromate replacement because of the environmental concerns associated with the traditional chromate treatment for corrosion prevention of aluminum alloys. Some of the possible approaches both chemical and physical are surveyed.
