在电极介质中,金属腐蚀试验发展到以电化学为基础的各种计算腐蚀速度的方法。这些方法主要是由某些电的参数出发测定腐蚀速度,要比以重量损失为基础的常用的试验快的多,这些电化学方法特别适用于腐蚀慢的金属,文献中人们在各种腐蚀情况下,使用这些方法,得到不同的结果。需要回顾一下,在腐蚀速度和电化学测定的结果之间简单的关系,这种关系是以非常有限的一些假设为条件,这些假设包括: In electrode media, metal corrosion testing have evolved to various electrochemical-based methods for calculating etch rates. These methods are mainly based on the determination of some of the electrical parameters of the corrosion rate of corrosion than the weight loss based on the commonly used test much faster, these electrochemical methods are particularly suitable for slow corrosion of metals, the literature in a variety of corrosion conditions Use these methods to get different results. It is worth recalling that the simple relationship between the rate of corrosion and the results of electrochemical measurements is conditional on a very limited number of assumptions, including:
