The corrosion behavior of specimens was evaluated in physiological solutions by electrochemical in vitro tests through linear and Tafel polarization tests. Cyclic polarization tests were performed for investigating of the specimen’s resistance against pitting. Finally, the corrosion resistance of untreated and modified specimens was compared. The results show that the corrosion resistance of 316L SS metallic implant is increased due to passivation surface treatment.   UR - https://journal.issiran.com/article_4827.html L1 - https://journal.issiran.com/article_4827_4112f5f21a19a17aa19c28ee25f59376.pdf ER -
