It is well known that different manufacturing technologies of titanium alloys have a substantial impact on its performance; for example the Ti-6Al-4V manufactured by selective laser melting (SLM) exhibit comparable even better mechanical properties than the counterpart produced by traditional manufacturing methods. Yet, the understanding of the corrosion behavior of SLM-produced materials is unknown. This chapter reviews the recent progress of the corrosion behavior of SLM-produced Tibased alloys, such as Ti-6Al-4V and Ti-TiB composite. The corrosion behavior and corrosion mechanism are compared and discussed between the SLM-produced titanium alloys and their counterparts processed by traditional methods.

Keywords: Composite, Corrosion behavior, Electrochemical methods, Microstructure, Selective laser melting, Ti-6Al-4V.
