Tip #14 - Corrosion types
Corrosion can be defined as the deterioration of material by reaction to its environment. Water intrusion is the principal cause of corrosion problems encountered in the field use of equipment. At normal atmospheric temperatures the moisture in the air is enough to start corrosive action. Oxygen is essential for corrosion to occur in water at ambient temperatures. Other factors that affect the tendency of a metal to corrode are:
- acidity or alkalinity of the conductive medium (pH factor)
- Stability of the corrosion products
- Biological organisms (particularly anaerobic bacteria)
- Variation in composition of the corrosive medium
- Temperature
