Paper Abstract

An influence of laser beam surface alloying of such substrates as Armco iron as well as the structural carbon steel (45) and the corrosion resistant chromium steel (2Cr13) on their performance under the cavitation erosion conditions was investigated. The powders of various additives were melted and alloyed by means of CO2 laser beam, and subsequently subjected to cavitation loading at the rotating disc facility. As a result of assays carried out four coatings of high (Co) or contributing to the increase in the impact toughness (Ni, Mn) were indicated as the responsible for the substantial improvement of the material wear properties.
