Study of the Behavior to Cavitation Erosion of Some Bronzes with Varying Percentages of Sn and Pb

Abstract

This paper presents the study of experimental researches on cavitation erosion behavior of some bronzes with varying percentages of Sn and Pb. These experimental researches were made in „Eftimie Murgu” University of Resita laboratories for three different alloys, namely CuSn5Pb20, CuSn8Pb15 and CuSn10Pb5. After rehabilitation of certain equipment that was operating with running water, some pieces made of bronzes, were replaced and there were taken samples for studying which were analyzed in order to identify the causes that led to their wear. Finally, these materials were compared, after the obtained results regarding the cavitation erosion resistance and after the metallographic analysis.
