Porous pieces were prepared with the alloy powder (TLM:Ti-Zr-Sn-Mo-Nb) and centre stick by means of sintering. The surface of porous pieces was modified with MAO. Another composite coating with BMP was prepared. The surface morphology, microstructure and composition of the three kinds of test pieces were analyzed. The new bone tissue around the coatings of these test pieces were evaluated according to animal implantation experiment. The results show that all of the three surface coatings have good biocompatibility. The PCI/HA group and PCI/HA/BMP group have excellent osteoconductivity and a good prospect of clinical application.
