Abstract

Ti-O/Ti-N duplex coatings were fabricated on titanium alloys by metal plasma immersion ion implantation and reactive plasma nitriding/oxidation. The purpose of Ti-O is to improve the blood compatibility, and that of Ti-N is to improve the mechanical properties. X-Ray diffraction (XRD), microhardness tests, pin-on-disk wear experiments, and platelet adhesion investigation were conducted to evaluate the properties and blood compatibility of the coatings. The results reveal that the blood compatibility of the Ti-O/Ti-N duplex coatings is better than that of low temperature isotropic pyrolytic carbon (LTIC). The microhardness of Ti-O/Ti-N duplex coatings can reach 14 GPa. The wear resistance is also much better than that of Ti6A14V alloy. The semiconductor nature of non-stoichiometric titanium oxide may be responsible for the observed improvement in the blood compatibility.
