Damage Caused by Particle Contamination

Mechanisms of Wear
Particle contamination can damage systems by causing a variety of types of wear. The primary types of wear are shown in the table below, along with the most common cause for that type of wear. Each of these wear mechanisms result in the generation of particulate contamination capable of causing further component damage.

Primary Cause
Abrasiver Verschleiß Particles between adjacent moving surfaces
Erosionsverschleiß Particles and high fluid velocity
Adhäsionsverschleiß Surface to surface contact (loss of oil film)
Ermüdungsverschleiß Particle damaged surfaces subjected to repeated stress
Corrosive Wear     Water or chemical
