The purpose of this paper is to study the corrosion resistance performance and requirements of AM biomedical implants as well as to characterize the corrosion behavior of Additive Manufactured 316L stainless steel in simulated physiological environment. The corrosion performance and mechanical properties of additively manufactured 316L stainless steel material in simulated physiological environment was studied. In the efforts of improving the reliability of Additive Manufactured biomedical devices, this research focuses on studying the corrosion, microstructural and mechanical properties of Additive Manufactured 316L stainless steel. It evaluates corrosion resistance through characterizing the corrosion behavior using cyclic anodic polarization tests in simulated physiological environment. In this experiment, the properties of 316L stainless steel parts manufactured using Selective Laser Melting SLM technique have been studied. Cyclic potentiodynamic polarization test indicated that additive manufactured materials had slightly lower corrosion resistance than the casted stainless steel parts of the same grade. This was evident by the difficulty of regenerating a stable and protective passive oxide layer at room temperature as well as the instability of passivation at higher temperatures. Moreover, the additive manufactured samples showed a higher yield strength than the casted samples but lower values for elongation and ultimate tensile stress.
