ABSTRACT

Mg-Zn-Ca metal glass shows good promising applications in biomaterials. MAO coating and Ca-P coating was applied on Mg69Zn27Ca4 metal glass in order to improve the alloy biodegradation resistance and biocompatibility. Microstructure observation, electrochemical experiment, immersion experiment and cell cytotoxicity experiment (MG63 cells) were carried out. The result revealed that Ca-P coating exhibited better degradation resistance than MAO coating due to its relatively thick and uniform structure. The cell cytotoxicity showed both coatings showed better bioactivity than the uncoated Mg69Zn27Ca4 metal glass. Moreover, Ca-P-coated samples had better bioactivity than those of MAO coated. Therefore, Ca-P coating improved not only the degradation resistance but also the bioactivity of Mg69Zn27Ca4 metal glass. Ca-P coating has a good promising application on Mg69Zn27Ca4 metal glass.

MAO涂层和Ca-P涂层对Mg69Zn27Ca4金属玻璃生物降解和生物相容性影响的对比研究

摘要

Mg-Zn-Ca金属玻璃在生物材料中显示出良好的应用前景。为了提高合金的抗生物降解性和生物相容性,在Mg 69 Zn 27 Ca 4金属玻璃上涂覆MAO涂层和Ca-P涂层。进行了微结构观察、电化学实验、浸没实验和细胞毒性实验(MG63细胞)。结果表明,Ca-P 涂层由于其相对较厚和均匀的结构而表现出比 MAO 涂层更好的抗降解性。细胞毒性表明两种涂层都比未涂层的 Mg 69 Zn 27 Ca 4表现出更好的生物活性金属玻璃。此外,Ca-P 包被的样品比 MAO 包被的样品具有更好的生物活性。因此,Ca-P涂层不仅提高了Mg 69 Zn 27 Ca 4金属玻璃的抗降解性,而且提高了生物活性。Ca-P涂层在Mg 69 Zn 27 Ca 4金属玻璃上具有良好的应用前景。
