Abstract Additive manufacturing (AM) is becoming increasingly important, making it possible to produce a product in a short time, to specific individual requirements, and even in the presence of the customer. This research is related to direct metal laser sintering of additive manufacturing. This new technology is increasingly being used in more sectors, for example in biomedical industry, where a damaged product can potentially endanger human life. Corrosion tests were carried out during our research. Cyclic voltammetry curves and corrosion rates were determined with a potentiostat. Two typical biocompatible implant materials were compared, a cobalt chromium alloy (powder metallurgy) and a titanium alloy (3D printed). The results will help in specifying the corrosion properties of additively manufactured materials.

Mechanical And Microstructural Properties

Duplex stainless steels (DSS) comprise equivalent proportions of ferrite (α) and austenite (γ) and exhibit excellent integration of mechanical and corrosion properties. The ferrite matrix provides better strength and stress corrosion resistance, whereas the austenite matrix accounts for good pitting corrosion resistance and toughness. Duplex stainless steels are widely utilized in the chemical industry, oil refineries, and machine industries. Direct energy deposition (DED) and powder bed fusion (PBF) are the two additive manufacturing techniques widely used for metals. This article covers the technologies like processing DSS by selective laser melting (SLM), variation in mechanical and microstructural properties of duplex stainless steels manufactured by additive manufacturing technique, and challenges of additive manufacturing processes.
