Fatigue wear in mechanical seal applications

In the actual application of mechanical seals, the friction surface is subjected to alternating stress, and the surface material is damaged due to fatigue. This type of damage often occurs in parts such as gears and rolling bearings.

The material transfer caused by the alternating stress to fatigue the surface material is called fatigue wear, sometimes also called contact fatigue. This kind of wear is sometimes called pitting (Pitting), which is the phenomenon of cavitation on the surface after material transfer. However, the high local stress on the surface causes the material to fatigue and cause wear. Pitting corrosion should be avoided, and fatigue wear is best.　　387.html,
