Ⅳ. Electrochemical Measurements in Various Environments―Electrochemical Measurements of Metallic Biomaterials―

Abstract

Electrochemical measurements such as polarization and impedance tests are used to evaluate the corrosion resistance of metallic biomaterials. The effect of in vivo biochemical and mechanical corrosion factors on the corrosion behavior of metallic biomaterials and the interaction between metal surface and cells are also examined with the electrochemical techniques. The findings will contribute to improve the corrosion resistance and biocompatibility of conventional and new metallic biomaterials including biodegradable metallic materials. The electrochemical techniques which are used to evaluate and to understand the effect of typical in vivo corrosion factors are introduced.
