abrasion erosion and cavitation erosion wear properties
CavitationWikipedia
Cavitation is a phenomenon in which the static pressure of the liquid reduces to below the liquid s vapour pressure leading to the formation of small vapor-filled cavities in the liquid.When subjected to higher pressure these cavities called "bubbles" or "voids" collapse and can generate shock waves that may damage machinery. These shock waves are strong when they are very close to the

What is Cavitation Erosion Definition from Corrosionpedia
Sep 18 2013 · Cavitation erosion is the process of surface deterioration and surface material loss due to the generation of vapor or gas pockets inside the flow of liquid. These pockets are formed due to low pressure well below the saturation vapor pressure of the liquid and erosion caused by the bombardment of vapor bubbles on the surface.
