Análisis de la biocompatibilidad de Ti6Al4V y acero inoxidable 316 LVM basado en efectos de pH, aplicando criterios de la norma ASTM F2129/Analysis of the biocompatibility of Ti6Al4V and stainless steel 316 LVM based on effects of pH, applying criteria of ASTM F2129 standard

The effect of pH on corrosion behaviour in stainless steel 316 LVM and alloy Ti6Al4V was studied by various electrochemical techniques such as cyclic potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The corrosion rate was calculated with Tafel extrapolations and the pitting corrosion was also analysed for each material in different conditions of concentration 3% of NaCl and range pH (4.5-6-7.5-10-12). The results exhibited that the conditions of pH 4,5 has negative effect in the corrosion rate for both materials compared with other pH.
