    摘要:

    為了提高純Ti的生物活性和抗感染性，采用微弧氧化(UMAO)制備多孔涂層，并以植酸(PA)偶聯(lián)骨碎補(bǔ)提取物(ERD)，并分析涂層結(jié)構(gòu)、形貌及性能。結(jié)果表明，隨著ERD濃度的提高，納米顆粒增多，有PO43-，P2O74-和O=P-O-生成；載藥12.5g/L的膜層摩擦磨損系數(shù)低，膜層結(jié)合力較高，為親水涂層，膜層的電位提高了0.32V，自腐蝕電流降低一個(gè)數(shù)量級(jí)，模擬體液浸泡有羥基磷灰石(HA)生成。純鈦表面通過超聲微弧氧化，植酸偶聯(lián)載藥的耐蝕性，結(jié)合力，生物活性均有提高。

    Abstract:

    To improve the bioactivity of surface of titanium and reduce infection rate of implantation, the porous coatings were prepared by ultrasonic micro arc oxidation (UMAO) and Rhizoma drynariae(ERD) coupled by phytic acid .Besides, the structure, surface morphology and performance were investigated. The results indicated that nanoSparticles of drug loading increased with concentration of ERD. The surface of coatings produced PO43-,P2O74- and O=P-O-. The friction coefficient of 12.5 g/L was lower .Also, the coating of 12.5 g/L had a better binding force and was hydrophilic. The potential increased by 0.33-0.45V and self-corrosion current decreased by a order of magnitude for concentration of 12.5 g/L. In conclusion, the corrosion resistance, binding force and bioactivity are improved by drug loading coupled with phytic acid after MAO on the magnesium.
