Abstract

Abstract: In order to improve the corrosion resistance of 316L stainless steel in marine environment, MnSi₂-reinforced 316L stainless steel composites were prepared by selective laser melting(SLM). The effect of laser power on density and corrosion resistance of the 316L stainless steel metal matrix composites was investigated by using Image-Pro Plus software, metallographic microscope, scanning electron microscope(SEM) and electrochemical work station. The corrosion resistance was evaluated by Tafel polarization curve and impedance spectrum, and the corrosion mechanism was revealed by pitting topography. The results show that adding MnSi₂ is an effective way to improve the corrosion resistance of 316L stainless steel. When the laser power reaches 190 W, the density of 2%MnSi₂/316L stainless steel composites is 99.80% and the corrosion potential is －0.053 V (vs SCE). At the same time, the 2% MnSi₂ can significantly improve the forming quality and corrosion resistance of the 316L stainless steel. The corrosion form is the corrosive pitting of chloride induced by chloride ions, and the pitting corrosion is mainly concentrated at the pore boundary.

Key words: MnSi₂/316L stainless steel composites, laser power, density, corrosion resistance, corrosive pitting
