利用金属在磷化液中腐蚀电流或腐蚀电压的变化研究磷化膜的生长过程和磷化膜完成的时间是一种简单、快速和方便的方法.用这种方法不仅能很容易地分析金属件在各种磷化液中的全部变化行为,而且可以很方便地确定最佳操作时间.
It is a simple, quick convenient method to measeure the corrosion potential or/ and current changes in phosphating solutions for studying the growing process of the phosphating films.This method can be used to detect easily the behaviour of metal workpie
