A Comparison of Corrosion Resistance of Stainless Steel Fabricated with Selective Laser Melting and Conventional Processing

Abstract

Selective laser melting is a recent technology which directly manufactures parts from metal powders. This paper mainly deals with the comparison of corrosion resistance behaviour of selective laser melted part and conventionally processed part. Moreover this paper also focuses on the microstructure and mechanical properties of the SLM and conventional part. The experimental studies reveals that SLM part have better corrosion resistance than the conventional. The corroded morphology of SLM part depicts fine sized pores, whereas in the case of conventional one the size of the pore is larger. Hence the mechanical properties of SLM part are significantly better than that of the conventional one.
