Whether the medium is gas or liquid – it doesn’t look like a pump impeller; without a pump, there’s no such thing as cavitation; in that case, it’s corrosion: lol
It looks like it’s for transporting gas; there must be corrosion
For the impeller of an axial flow pump, this phenomenon is definitely caused by corrosion
It should be pitting caused by chloride ions
Axial flow pump impeller: corrosion and erosion by the medium, cavitation caused by small bubbles in the medium; also related to the material of the impeller blades and their finish quality
Abrasion. Cavitation usually occurs at the root of the impeller; in your case, it’s occurring all over.
