 This research examined the effects of remelting and solidifying layers of an albast alloy with an electric arc to reduce cavitation erosion. The results showed that the remelting process increased the hardness of the surface layer and decreased the erosion rate. This was attributed to the improved microstructural homogeneity and grain refinement caused by the remelting process.
