引言由于绝大多数腐蚀过程的电化学本质,电化学测试技术已成为获得金属腐蚀速度的重要手段。原则上说,只要把测得的腐蚀电流运用法拉第定律就可以方便地换算成腐蚀速率。换算时的特征参数是电化当量(或简称当量)。确定纯金属的当量是简单的。然而,对 Introduction Due to the electrochemical nature of most corrosion processes, electrochemical testing techniques have become an important tool for obtaining metal corrosion rates. In principle, as long as the measured corrosion current Faraday’s law can be easily converted into the corrosion rate. Conversion of the characteristic parameters is the electrochemical equivalent (or simply equivalent). Determining the equivalent of pure metal is straightforward. However, yes
