A hydroxyapatite(HAp)film was fabricated on the surface of Ti-29Nb-13Ta-4.6Zr(TNTZ)using a metal-organic chemical vapor deposition(MOCVD)technique, and the mechanical biocompatibility and HAp formability of HApcoated TNTZ were evaluated and discussed in this study. HAp film is fabricated on the surface of TNTZ by controlling the heating temperature of the source bis-dipivaloylmethanatocalcium((Ca(dpm)2)and(C 6H5O)3PO). An α-phase precipitates in the TNTZ matrix after heating the substrate, and the mechanical properties and Young's modulus of HApcoated TNTZ are improved. HAp-coated TNTZ maintains excellent mechanical biocompatibility. The formability of HAp on HAp-coated TNTZ in Hank's balanced salt solution is better than that of HAp on non-coated TNTZ.
