What is the Principle of Electrochemical Corrosion?
1 Answers
Electrochemical corrosion occurs when a metal material comes into contact with an electrolyte solution, leading to corrosion through electrode reactions. Here is a partial introduction to electrochemical corrosion: 1. Introduction: Electrochemical corrosion is a type of redox reaction. In this reaction, the metal loses electrons and becomes oxidized, a process known as the anodic reaction. The products of this reaction are metal ions that enter the medium or metal oxides (or insoluble metal salts) that form on the metal surface. Substances in the medium gain electrons from the metal surface and become reduced, a process known as the cathodic reaction. 2. Characteristics of the Reaction Process: Under certain conditions, oxidizers in non-electrolytes directly interact with atoms on the metal surface to form corrosion products.
