The corrosion current is a typical corrosion value which can be related, for example, to the corrosion rate. The information obtained from both values is necessary when studying the corrosion state of a given system. The aim of this tutorial is to show to the user how to determine the corrosion current using simple graphic tools on EC-Lab linked to the Tafel equation: Tafel fit and R fit. VMP3多通道電化學工作站-16通道
