The study of cavitation is of topical interest in both physical and biological sciences.
The surface roughness changes the effect of cavitation on a material surface.
Cavitation can damage and erode solid materials by the following mechanisms: generation of shock waves due to symmetric bubble implosion and formation of micro jets due non-symmetric bubble implosion [6, 7].
It is presumed that the blotch free smooth surface material creates more micro bubbles, thus the cavitation is more in it than the rough surface material.
