【摘要】：采用堿液處理醫(yī)用鈦表面制備出微納米分級(jí)多孔結(jié)構(gòu)膜層,通過(guò)酸處理以及不同溫度熱處理對(duì)微納米分級(jí)多孔膜改性以提高其生物活性。利用SEM、EDS和XRD分析鈦表面微納米分級(jí)多孔膜的形貌、化學(xué)組成和物相組成,探討熱處理溫度對(duì)鈦表面微納米分級(jí)多孔膜結(jié)構(gòu)特征的影響規(guī)律。結(jié)果表明,當(dāng)熱處理溫度低于750℃時(shí),樣品表面的微納米分級(jí)多孔膜層形貌特征保持不變;當(dāng)熱處理溫度為550℃時(shí),鈦表面微納米分級(jí)多孔膜物相主要是結(jié)晶良好的銳鈦礦型二氧化鈦,具有良好的生物活性。
[Abstract]:The porous membrane was prepared by alkali treatment on the surface of medical titanium. The porous membrane was modified by acid treatment and heat treatment at different temperature to improve the biological activity of the membrane. SEM was used to improve the bioactivity of the membrane. EDS and XRD were used to analyze the morphology, chemical composition and phase composition of micro and nano graded porous films on titanium surface. The effect of heat treatment temperature on the structure characteristics of micro and nano graded porous films on titanium surface was discussed. When the heat treatment temperature is lower than 750 鈩，
