The effect of remelting on the resistance to cavitation erosion property was investigated and the result was compared with that of 304 stainless steel and weld–cladding layer. The alloy layer was analyzed by weight loss analysis, scanning electron microscopy (SEM) and X–ray diffractometer (XRD). Results indicating that the grain size in remelting layer was smaller. The resistance to cavitation erosion property of overlaying and remelting layer was better than that of 304 stainless steel and remelting layer is even better than that of overlaying. Phase transformation from austenite to martensite happened in the cavitation erosion process, which absorbed the energy of cavitation erosion and delayed the process of cavitation erosion. The refined grains by TIG remelting process in the overlaying alloy prevented the development of cracks and enhanced the cavitation erosion resistance property effectively.
