Abstract

Scanning electron microscopic investigations of particles produced by cavitation erosion and fracture surfaces revealed that the dominant mode of cavitation erosion is fatigue failure in 304 stainless steel. In addition, the surface roughness facilitates the fall-off-particles, especially the longitudinal particles. The particles gathered can be classified into three types according to their shapes, namely longitudinal, triangular and mixed quadrangular hexagon. The spherical particles, which were observed previously in some reports on cavitation erosion, were not observed in this work.
