Outline of Final Research Achievements

In this research, impact-fretting wear tester in corrosive environment was developed, also corrosive wear properties of bio-compatible materials for artificial hip joints were evaluated. Furthermore, I attempted a model analysis of impact-fretting wear.
Corrosion resistant materials such as Type304, Type316L and CoCr alloy were evaluated corrosion properties with polarization tests. Then, the wear volume of impact-fretting was clarified to be largely dependent on a corrosion volume of a fresh surface. Moreover, we proposed a wear model which considered corrosion effects.
