Outline of Final Research Achievements

Degradation and function, such as material strength, shape memory effects, superelasticity and corrosion resistance in biological environment, induced by the hydrogen absorption and states of metallic biomaterials have been elucidated in the present study. In addition, by controlling the amount of absorbed hydrogen and hydrogen states, the balance between degradation and function has been evaluated from the multilateral standpoint of strength of materials, biomedical materials and electrochemistry. The obtained findings are expected to the fundamental guide for the improvement of materials reliability for metallic biomaterials.
