Corrosion measurement techniques and its experimental results of metallic biomaterials in vivo and in vitro are reviewed. The corrosion phenomena of metallic biomaterials used for artificial joints, bone plates, etc. are discussed based on empirical data. Dissolution, open circuit potential, repassivation potential, and repassivation current are measured. Also, polarization, AC impedance, and surface analyses are employed in the field of biomaterials. However, test solutions used for the measurements are characteristic in biomaterial research. The compositions of the solutions are simulated as body fluid, controlling temperature, pH, and dissolved oxygen concentration.
