Abstract

The dynamics of passive oxide films on metallic biomaterials immersed in physiological solutions is studied with Electrochemical Atomic Force Microscopy and Step Polarization Impedance Spectroscopy. Direct correlation between surface dynamic changes and electrochemical and impedance behavior is reported for a CoCrMo alloy and NiTi. Oxide film hydration and potential result in active remodeling and growth of the surface oxides. The role of these dynamic changes in terms of biological interaction, protein adsorption, etc. are discussed.
