Types Of Corrosion
While there are a number of forms or types of corrosion, it is rare that a corroding structure or component will suffer from only one. While some forms of corrosion may be unique they are all interrelated.
The 4 Elements Of Corrosion
Before corrosion can take place four conditions must be satisfied:
- The presence of a corrodible metal or alloy (anode)
- The presence of a dissimilar conductive material that has a lesser tendency to corrode (cathode)
- The presence of an electrolyte, fresh or salt water
- Electrical contact between the anode and the cathode
The elimination of any of the above conditions will halt the corrosion process!

Hydrogen Induced Cracking
Results in the brittle failure of otherwise ductile or malleable materials when exposed to an environment where hydrogen can enter the metal. This is a common problem in processes or conditions involving wet hydrogen sulfide such as in oil fields.

Erosion or Flow Corrosion
Caused by the corrosive fluid flowing through an unprotected metal surface such as a pipe.

Pitting Corrosion
A deep, focused attack that can cause rapid penetration of the metal. Pitting is one of the most destructive forms of corrosion. It is also difficult to detect because of the generally small size of the pit or hole.

Intergranular Corrosion

Microbial Corrosion
Stress Corrosion Cracking
Corrosion Fatigue
Uniform Corrosion
Fretting Corrosion
Crevice Corrosion
Selective Leaching or De-alloying
Galvanic Corrosion
Stray Voltage Corrosion
Exfoliation corrosion
