Paper Abstract

Cavitation resistance of 45 and 2Cr13 steels with surface layers enriched with Hf, SiC and AlNi was investigated. Each doped element was spread over the sample surface and subsequently melted with core material using CO2 laser beam. The cavitation tests carried out at the rotating disk facility revealed multiple (5-10 fold) increase of erosion resistance of the processed materials. This effect was not always related to observed changes of microhardness. Moreover, both microstructure of the surface layer and of core material were found to influenced cavitation erosion resistance.
