Abstract :
The purpose of this paper is to prove the reliability of artificial hip joints’ surface generated by the electrolytically treated grinding process; the evaluation was carried out in a hip simulator and animal tests. The evaluation indicated that the fabricated hyper-hemispherical shaped artificial hip joints presented a high quality smoother surface than 10 nm in Ra. The fabricated surface also showed its ability to prevent crystalline phase transition during the hip simulation test, suggesting that the stably modified layer was generated via grinding process. The results of animal test showed that the fabricated surface could have a highly-improved biocompatibility.
