Question

Define corrosion. mention the type of corrosion​

Answer 1

It’s common for high-performance structural components to experience some form of corrosion regardless of what type of material is used and corrosion resistant coatings can increase the lifespan of a part, as well as reduce maintenance and replacement costs. In order to select the appropriate coating, though, it’s important to identify what kind of corrosion a part is prone to. Based on how a part is used and what conditions it’s exposed to, the kind of corrosion that develops may differ.

There are five general types of corrosion: galvanic, stress cracking, general, localized and caustic agent corrosion.

When metal surface is attacked by oxygen , water vapour, other components of air ( O2, SO2, H2S etc) and acids, metal surface loses its strength and shine, such process of weakening metal is known as corrosion.
