dc.description.abstract The surfaces of AISI 316L stainless steel were laser alloyed with ruthenium powder and a mixture of ruthenium and nickel powders using a cw Nd:YAG laser set at fixed operating parameters. The microstructure, elemental composition, and corrosion characteristics of the alloyed zone were analyzed using optical and scanning electron microscopy (SEM), energy dispersive Xray spectroscopy (EDX), and corrosion potential measurements. The depth of alloyed zone was measured using the AxioVision programand found to be approximately 1.8mmfor all the alloyed specimens. Hardness profile measurements through the surface substrate interface showed a significant increase from 160HV for the substrate to a maximum of 247HV for the alloyed layer. The sample laser alloyed with 80wt% Ni-20wt% presented the most noble corrosion potential (Ecorr) of -0.18 V and the lowest corrosion current density (icorr). en_US
