    摘要:

    采用等離子噴涂技術(shù)在醫(yī)用純鈦基體表面構(gòu)建出微納米多級(jí)結(jié)構(gòu)鉭涂層。利用SEM、EDS和XRD分析微納米多結(jié)構(gòu)鉭涂層的形貌、化學(xué)組成和物相組成，并根據(jù)ASTM C633-79評(píng)價(jià)涂層與基底的結(jié)合強(qiáng)度；采用牛血清蛋白(BSA)對(duì)比研究了鈦基鉭涂層與醫(yī)用純鈦對(duì)照樣表面的蛋白吸附行為。結(jié)果表明，在噴涂距離為110 mm、噴涂功率為30 kW時(shí)制備的鈦基鉭涂層具有典型微納米多級(jí)結(jié)構(gòu)特征，且與基體結(jié)合強(qiáng)度好、Ta相對(duì)含量高；蛋白吸附實(shí)驗(yàn)表明鈦基鉭涂層表面蛋白吸附量均高于醫(yī)用純鈦對(duì)照樣，具有良好的蛋白吸附能力。

    Abstract:

    Micro/nano multi-level structure tantalum coating was prepared on medical titanium substrate surface using plasma spraying technique. The surface morphology, chemical composition and phase composition were analyzed by SEM, EDS and XRD, and the adhesion between substrate and coating was investigated by tensile method. The surface adsorption amount of protein of micro/nano multi-level tantalum coating and titanium substrate was compared by using BSA. The result showed that when the titanium-based tantalum coating was prepared under the spray distance was 110 mm and spray power was 30 kW, typical multi-level structural features can be seen, combined with good binding force and high Ta phase content; protein adsorption test showed that titanium-based tantalum coatings have good protein adsorption capacity, whose adsorption amount were higher than control samples.
