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.
Particles between adjacent moving surfaces
Particles and high fluid velocity
Surface to surface contact (loss of oil film)
Particle damaged surfaces subjected to repeated stress
Water or chemical
