چکیده
Abstract 3D metal printing process has attracted increasing attention in recent years due to advantages, such as flexibility and rapid prototyping. This study aims investigate the orientation effect of electropolishing characteristics on different surfaces 316L stainless steel fabricated by laser powder bed fusion (L-PBF), considering that rough surface printed parts is a key factor limiting its applications industry. The corresponding building selective melting are studied. Experimental results show electrolyte temperature critical importance electropolishing, especially for vertical direction layering plane. finish electropolished affected defects generated during L-PBF process. Thus, higher roughness Sa than horizontal surface. X-ray photoelectron spectroscopy spectra Cr/Fe element ratio presents corrosion resistance measuring anodic polarization curves fitting equivalent circuit experimental electrochemical impedance spectroscopy.

IMPROVING PITTING CORROSION OF 304 STAINLESS STEEL BY ELECTROPOLISHING TECHNIQUE
Several surface modification techniques such as ion implantation, surface laser melting, have been employed to improve pitting corrosion resistance of stainless steel. Electropolishing is a technique in which the surface roughness is eliminated through a selective electrochemical dissolution. The effect of electropolishing on pitting corrosion of 304 stainless steel (SS) was investigated employ...
