Cavitation corrosion, or cavitation erosion, is a type of corrosion experienced by materials when exposed to a liquid that contains cavitating bubbles. Cavitating bubbles are micro-sized gas bubbles that form in a liquid due to low pressure, and then collapse violently due to an increase in pressure. This can cause damage to the surface of the material and lead to corrosion.

Cavitation corrosion can happen when a material is placed in a liquid that has a high velocity. This can cause the formation of the cavitating bubbles which will then collapse at a high speed. This creates shockwaves which can cause the material to corrode. Cavitation erosion can also occur when the pressure difference between two points is high. This can increase the velocity at which the bubbles collapse, and increase the amount of damage caused.

Cavitation corrosion is most common in water systems, such as pipes, valves, pumps, and other equipment. It is important to ensure that these systems are regularly inspected and maintained in order to prevent corrosion. In addition, materials that are exposed to cavitating bubbles should be chosen carefully, as some materials are more resistant to cavitation corrosion than others.

Cavitation corrosion can also be prevented by using protective coatings on the surface of the material. This will help to reduce the impact of the shockwaves and limit damage to the material. Additionally, it is important to monitor the velocity of the liquid in order to reduce the chances of cavitation corrosion occurring.

In conclusion, cavitation corrosion is a type of corrosion that is caused by the collapse of cavitating bubbles due to pressure changes. It can be particularly damaging for materials in water systems, and it is important to take steps to reduce the chances of corrosion occurring. This includes regularly inspecting and maintaining equipment, choosing the right materials, and using protective coatings.
