    Abstract:

    By the plasma spraying technology, nitrogen silicon zirconium-hydroxyl apatite (ZrSiN-HA) compound coating was prepared on the surface of pure titanium substrate and implanted with the mandible of the experimental animal. The appearance morphology of the compound coating was observed and analyzed by the scanning electron microscope. The bone binding forces of four groups of samples, e.g. ZrSiN-HA, ZrSiN, HA and pure titanium were examined and compared by the electronic universal testing machine; the appearance morphologies of the fracture regions of each group were observed. The corrosion resistance of the four groups of coatings was compared and examined on the electrochemistry corrosion testing system. The results indicate that the implant surface sprayed with the ZrSiN-HA is more compact than that sprayed with the HA. The crystallization is obvious. Compared with the other coatings, the ZrSiN-HA coating has the highest bone binding force, and its anti-corrosive performance is the best. The ZrSiN-HA coating application is beneficial to the long-term retention of implant and can be applied in the human body
