Cavitation erosion resistance of high-entropy FeCoCrNiMo_XB_0.2 coatings cladded by laser

The cavitation erosion resistance of high-entropy FeCoCrNiMoXB0.2(X = 0, 0.5, 1), coatings cladded by laser was studied. The test was processed by a magnetostrictive cavitation method in both distilled water and 3.5 wt-% NaCl solution. It was observed that the mass-loss rate of the coatings rarely increased or even decreased in the first few hours. This study verified that the formation of cavitation pits and extend of cracks due to the...
