| The present study has investigated the electrochemical behaviors involved in (a) Microbiogically Influenced Corrosion (MIC) of stainless steel (SS-304) using Electrochemical Noise (ECN) in artificial saliva solutions, (b) commercial TiO2 nanoparticles-coated Ti-6Al-4V, and (c) the effect of LASER treatment on Ti-6Al-4V, using TAFEL analysis and Electrochemical Impedance Spectroscopy (EIS) in simulated biofluids. Corrosion behaviors of SS-304, attached with Acidithiobacilus ferrooxidans (ATF) bacteria and exposed to artificial saliva solutions have been monitored by using a non-destructive measurement (ECN analysis) and signal processing techniques. Corrosion behaviors of the TiO2 nanoparticles coated bioimplant Ti-6Al-4V were exposed to three different simulated biofluids (SBF) were studied using electrochemical techniques including open circuit voltage (OCV), TAFEL analysis, and EIS. A commercial Ti-6Al-4V alloy was treated with a pulsed-wave Nd:YAG laser under various process conditions. The corrosion behaviors of bare and laser-treated Ti-6Al-4V exposed to three different SBFs were studied by using various electrochemical techniques. |
