Corrosion - Type of Corrosion

Intro

In our environment, there exists many forms of corrosion although they do eventually causing the same thing, which is making useful product becoming defective product (i.e-a nail becomes rusty and looses its function or purpose). Recognising what type of corrosion they are is quite useful as this will allow us to control the corrosion in a more structured way due to specific type of corrosion behaves in specific parameters.

Grouping or Type of Corrosion

In general, corrosion can be categorised into 5 types, which are as followed:

1. Low temperature (aqueous) corrosion - [damage due to electrochemical reaction]
2. Mechanical assisted corrosion -[damage due to mechanical effect or metallurgical degradation]
3. Environmental assisted corrosion -  [combine action of tensile stress & corrosion in specific environment]
4. High temperature attack -[damage without presence of aqueous electrolyte, typically above 400F]
5. Microbiological induced corrosion  -[damage due to presence & activity of microbiological organism]

The examples and details for each type of corrosion will be written in several separate posts.
