“…It is especially met in turbines, ship propellers, pumps or motor engines. The results of numerous works prove that laser surface modification leads to the substantial increase of the materials cavitation erosion resistance [1][2][3][4][5][6][7][8][9]. In recent years, some researches attempted to improve the anti-cavitation properties of steels by enriching their surfaces layers with various kinds of metal or ceramic particles.…”

The laser surface alloying of 18/8 stainless steel with Mn, was carried out by 6 kW cw CO2 laser. The microstructure, chemical composition and phase identification of the modified layer were examined using scanning electron microscopy, energy dispersive X-ray spectroscopy and Xray diffractometry, respectively. Cavitation behavior of produced layers was investigated in a rotating disc facility. Cavitation properties of laser-processed steel were calculated in the initial stage of erosion, on the surface of about 4 mm2, on which cavitation intensity was constant. As a property characterizing the cavitation erosion resistance of materials was proposed for the depth of strain hardening. It was found that presence of manganese in the amount of 7.31% causes the highest increase hardness after alloying and the lowest depth of strain hardening due to cavitation loading.
