Electrochemical behavior of 316L stainless steel in simulated body fluid solution
Résumé
Electrochemical behavior of 316L stainless steel material according to immersion time in simulated body fluid solution was studied by measurement of open circuit potential (Eo), Tafel polarization and electrochemical impedance methods. The increase of both Eo and Rp, while the decrease of icorr showed the formation of apatite film on the surface of 316L stainless steel in test time. The results of measurement infrared IR spectra, SEM, X-ray and EDX indicated that the formation of apatite film was relatively thick after 17 days immersion and characterized the structure of HAp
