What is cavitation wear?

Cavitation wear is a special fatigue pitting corrosion phenomenon of the working surface material of parts under the repeated action of the continuous formation and collapse of bubbles in the liquid, which produces huge impact forces and high temperatures in an instant.
After the surface material of the cavitation parts gradually detaches due to fatigue, pitting pits appear, and then expand into a foam sponge shape. When cavitation occurs in Hanzhong, the expansion speed is very fast and the depth can be quite large.

Cavitation is a relatively complex comprehensive form of damage. It is not only damage caused by mechanical force (impact), but also damage caused by the chemical and electrochemical effects of liquid. In addition, cavitation particles can become abrasives and wear related working surfaces.
