    摘要:

    采用等離子噴涂技術在純鈦表面制備氮硅鋯-羥基磷灰石(ZrSiN-HA)復合涂層并植入實驗動物下頜骨。利用掃描電鏡、電子萬能材料試驗機對比檢測ZrSiN-HA、ZrSiN、HA與純鈦對照4組涂層的骨結合力,觀測各組斷裂區(qū)域的形貌,并分析復合涂層的表面形貌;用電化學腐蝕測試系統(tǒng)對比檢測4組涂層的耐腐蝕性。試驗結果表明,種植體表面噴涂ZrSiN-HA后較單純噴涂HA的表面更加致密,結晶化明顯;ZrSiN-HA涂層與其他涂層相比骨結合力最高,耐腐蝕性能最強。ZrSiN-HA涂層的應用有利于種植體的長期固位,可以應用于人體,對齒科修復體具有巨大的潛在應用價值

    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
