Reducing contamination in the oil will also help eliminate adhesive wear. Cavitation occurs when entrained air or gas bubbles collapse. When the collapse occurs against the surface of internal components, cracks and pits can be formed. Controlling foaming characteristics of oil with an anti-foam additive can help reduce cavitation. Corrosive Wear is caused by a chemical reaction that actually removes material from a component surface.
Corrosion can be a direct result of acidic oxidation.
A random electrical current can also cause corrosion. Electrical current corrosion results in welding and pitting of the wear surface. The presence of water or combustion products can promote corrosive wear. Cutting Wear can be caused when an abrasive particle has imbedded itself in a soft surface. Equipment imbalance or misalignment can contribute to cutting wear.
