Abstract

The paper deals with the topic of the determination of erosion effects of a pulsating water jet impinging the surface of aluminium alloy samples treated by various techniques (rough and fine milling, planing and rolling). The influence of the initial surface topography on the final topography of the sample exposed to the pulsating water jet was investigated. Erosion of surface layers was analysed and discussed in relation to the traversing velocity of the jet. It was found that initial surface properties have a significant impact on the final topography. Degree of the surface erosion was determined by the measurement of the surface parameter Ra.
