Corrosion is an electrochemical process by which materials are deteriorated. In many cases—and especially when liquids are present—it involves chemistry. During corrosion, electrons from distinct areas of a metal surface flow to different areas of the metal through an atmosphere capable of conducting ions. In other words, electrochemistry is a crucial aspect of truly understanding and preventing corrosion.
A recent article in CorrosionPedia, explores these electrochemical reactions with explanations of the Daniell cell, the anodic method, the cathodic method, Faraday’s laws, and surface area effects. The idea is if we thoroughly understand the electrochemistry of corrosion, we can better learn how to prevent it.
