3.其它实验室腐蚀试验方法的发展腐蚀试验的目的是为了验证腐蚀机理、测定金属的腐蚀速度、金属材料发生某种腐蚀的敏感性、腐蚀产物的组成与结构分析、防腐方法的效果等等.涉及到试验条件的制定(包括腐蚀介质组成与浓度、试验期限、浸蚀方法等等)和腐蚀后试片的评定方法.a.腐蚀速度的测量方法重量法是测量腐蚀速度的一种经典方法.在四十年代以前主要是使用普通的分析天平.1942年,
3. Development of other laboratory corrosion test methods The purpose of the corrosion test is to verify the corrosion mechanism, determine the corrosion rate of the metal, the sensitivity of the metal material to some corrosion, the composition and structure analysis of the corrosion product, the effect of the corrosion protection method, and the like Involved in the development of test conditions (including the composition and concentration of corrosive media, test duration, etching methods, etc.) and evaluation methods of corrosion specimens.a Measurement of corrosion rate Gravimetric method is a classic measure of corrosion rate Method. Before the 1940s, the common analytical balance was used. In 1942,
