Abstract

316L stainless steel powders were clad onto AISI 1045 steel substrate using laser multi-track overlapping process.The microstructure and anodic polarization corrosion behavior in 2mol NaCl,1mol FeCl3 and 0.5mol HCl aqueous solutions of the clad layer and its commercial counterpart bulk 316L stainless steel were comparatively investigated.The chemical composition of the clad layer resulted from dilution from the substrate is quite different from that of the original 316L stainless steel powders,the final microstructure of the clad layer comprised predominant martensite and very small amount of residual austenite.The anodic polarization behavior of the clad layer was similar to that of its commercial counterpart bulk in the aqueous solutions mentioned above.There exists Tafel relationship between the superpotential of anodic and cathodic polarization and current for both the clad layer and the bulk.The clad layer displays good passive performance and pitting corrosion resistance.Compared with the bulk,however,the clad layer has larger self-corrosive current density,lower potential and smaller polarization resistance,and its corrosion resistance slightly degrades.
