| Abstract Scope |
Cost-effective, non-spherical Ti-6Al-4V powders produced by hydride-dehydride (HDH) method are processed by laser powder bed fusion (LPBF) for implant applications. It is well-established that the microstructure of the LPBF processed part will considerably affect the corrosion behavior in saline water. Thus, it is vital to conduct a study on the effect of the LPBF process on the microstructure of the as-build and post process heat-treatment parts. The electrochemical behavior is studied in saline solutions of 0.9, 3.5, and 10% NaCl. Grain structure and phase fraction are studied by optical microscopy and electron backscatter diffraction to investigate the correlation between microstructure and post processing on the electrochemical properties upon exposure to corrosive conditions. Evaluating the effect of post heat treatment on corrosion behavior of non-spherical HDH LPBF Ti-6Al-4V printed samples, can sustain the integrity of the newly introduced powders to be replaced with expensive spherical Ti-6Al-4V powders. |
