主 题：selective laser melting layered structure Ti6Al4V/316L plasma oxidizing TiO_(2) corrosion
摘 要：Selective Laser Melting(SLM),one of the metal additive manufacturing methods in the powder bed,is frequently used in the production of 316L stainless steel *** this study,the effect of duplex surface modification(metal additive manufacturing and plasma oxidizing)on the corrosion resistance of 316L was ***6Al4V layer was formed by additive manufacturing on 316L produced by selective laser melting *** obtained layered Ti6Al4V/316L samples were oxidized by plasma at 650℃–750℃ and 1 h–4 h parameter ***_(2)ceramic layer was formed on the Ti6Al4V/316L structure by plasma oxidation process in several layer *** properties of the TiO_(2)layer were determined by Open Circuit Potential(OCP),potentiodynamic polarization,and Electrochemical Impedance Spectroscopy(EIS)tests in Simulated Body Fluid(SBF)***,the surface characterizations of the samples were determined by the Vickers micro-hardness tester,Scanning Electron Microscopy(SEM),and X-Ray Diffractometer(XRD)*** the results,it was obtained that the corrosion resistance of the plasma oxidized was higher than the untreated 316L and layered Ti6Al4V/316L *** best corrosion resistance was obtained under the 750℃ and 4 h parameter conditions because of the increasing plasma oxidizing time and temperature.
