Additive manufacturing (AM) offers flexibility and customization along with economic advantages. In this
study, additively manufactured and wrought UNS R56400 (Ti-6Al-4V) were exposed to phosphatebuffered
saline (PBS) at various pH values, simulating a range of post-operative conditions. The corrosion behavior of these alloys was investigated per ASTM F2129-19a and ASTM G59-97, followed by potentiodynamic polarization scans. Microstructural characterization was conducted using scanning electron microscopy coupled with energy dispersive X-ray spectrometry.
