摘要	Iso-material manufacturing of 17-4PH stainless steel (17-4PH SS) by laser surface melting (LSM) is applied at various laser energy densities, which is different from additive manufacturing and subtractive manufacturing as this environment-friendly technology can improve materials property without changing the chemical composition and efficiently conserve expensive materials. Experimental results show that when the laser energy density is reduced from 44.4 to 26.7 J/mm2, the average grain size of 17-4PH SS substrate can be refined from 10.935 to 1.358 mu m. The residual stress (Rs), nano-hardness (H) and elastic modulus (E) of the melting layers increase with the decrease of laser energy density. The values of H/E and H3/E2 exhibit a trend of first increase and then decrease. The LSMed-1300 sample exhibits the highest corrosion resistance due to the comprehensive influence of grain size, precipitations and residual stress. The cavitation erosion (CE) resistance of the four LSMed samples is higher than that of the 17-4PH SS substrate in 3.5wt.% NaCl solution, and the LSMed-1300 displays the highest CE resistance. LSM 17-4PH SS prepared in this study shows good corrosion resistance and CE performance and has a good application prospect in the field of marine engineering.
