Metastable pitting corrosion behavior of laser powder bed fusion produced Ti-6Al-4V in Hank’s solution
TL;DR: In this article , the authors investigated the metastable pitting corrosion behavior of LPBF-produced Ti-6Al-4V in Hank's solution by electrochemical methods and found that the passive films formed on the LPBF produced sample exhibit a higher flux of oxygen vacancies, resulting in the absorption of more aggressive ions (e.g., Cl-) thereby producing more cation vacancies.

The corrosion behavior of Ti6Al4V fabricated by selective laser melting in the artificial saliva with different fluoride concentrations and pH values
TL;DR: In this article, the corrosion behavior of the SLM and wrought Ti6Al4V is comparatively investigated, and the critical NaF concentrations of SLM in the three cases of pH 2, 4 and 6 are 0.0020m, 0.080m and 0.10m, respectively.
