How to Prevent Corrosion in Metals: 5 Measures | Metallurgy

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 [...]

Coating of Metals: Metallic and Non-Metallic | Metallurgy

In this article we article we will discuss about the metallic and non-metallic types of coating metals. Cost is a very important factor while choosing an engineering material. In majority of applications of metals, the importance of the corrosion factor does not warrant the use of expensive corrosion-resistant alloys. Thus, when an easily corrodible alloy like steel is used, some [...]
