In this article we will discuss about:- 1. Introduction to Corrosion 2. Classification of Corrosion 3. Rate 4. Corrosion Rates from Polarisation and Mixed Potential Theory. Introduction to Corrosion: Corrosion is responsible for colossal loss of materials occurring everywhere every moment involving billions and billions of rupees annually. It is one of the most serious destructive agents, and is one [...]
Corrosion occurs when metals come in contact with a corrosive atmosphere. Thus, corrosion can be prevented by: 1. Geometrical Design 2. Proper Selection of Material 3. Modification of corrosive environment 4. Cathodic Protection 5. Anodic Protection. The most effective and economical method of preventing corrosion is to choose the most suitable geometrical design, most suitable material and then choose most [...]
Corrosion is a very complex phenomenon. However, depending on the form, appearance and the distribution of the attack, corrosion is classified industrially in following types: 1. Uniform Corrosion 2. Atmospheric Corrosion 3. Inter-Granular Corrosion 4. Pitting Corrosion 5. Crevice Corrosion 6. Stress-Corrosion Cracking 7. Hydrogen-Embrittlement 8. Corrosion-Fatigue 9. Erosion-Corrosion and Few Others. Types # 1. Uniform Corrosion: If corrosion is [...]
