Cavitation Erosion Resistance Influence of Material Properties [PDF]

Advances in Materials Science, 2019
Abstract The cavitation erosion is the phenomena that causes degradation of fluid flow machinery components due to repetitive implosion of cavitation bubbles adjacent to the solid surface. Cavitation erosion is a complex phenomenon, which includes not only hydrodynamic factors of liquid, but also properties of erodible material e.g ...
