一、前言防止金属的腐蚀有多种方法,其中防蚀涂装用得最广泛.近年来涂料和涂装技术发展很快,已研究出实用于各种需要的各种各样涂料品种和涂装方法.然而,有关涂膜的防蚀性能、耐久性能的检测,一般依旧采用自然曝露方法.这种方法可靠性最好,最能反应实际防蚀效果,但存在试验周期长,试验结果没有普遍性的缺点.因为想从一种曝露条件下的试验结果推论到其它条件下相当困难.并且人为误差使结果出入很大.所以依靠曝露试验是难以适应涂料和涂装技术的发展.为此人们提出了许多人工加速试验 Preface Prevention of metal corrosion There are many ways, including anti-corrosion coating is the most widely used in recent years, paint and coating technology developed rapidly, has developed a variety of practical needs for a variety of coating species and coating However, the coating on the corrosion resistance, durability testing, the general still use the natural exposure method.This method is the best reliability, the best response to the actual anti-corrosion effect, but there is a long test period, the test results are not The disadvantage of universality is that it is quite difficult to infer from the experimental results under one exposure condition that the other conditions are quite difficult and the human error makes the result so large that exposure testing is difficult to adapt to the development of coating and coating technologies. People have put forward many artificial accelerated tests
