摘要：

Hydroxyapatite (HA) reinforced with sub-micrometer Al(2)O(3) and carbon nanotubes (CNTs) has been synthesized as a coating on the Ti-6Al-4V substrate via plasma spraying. The addition of Al(2)O(3) and CNTs to HA has shown improvement in the hardness and elastic modulus by 65% and 50%, respectively, when compared to HA. Consequently, HA-Al(2)O(3)-CNT coatings have been nano-scratched to understand their wear performance. Reinforcement of HA by Al(2)O(3) shows a decrease in the wear volume by more than 13 times, whereas HA-Al(2)O(3)-CNT coating demonstrated further wear volume reduction of five times compared to that of HA-Al(2)O(3) coating.
