摘要： 采用微弧氧化工艺在钛基体表面形成陶瓷涂层, 通过SEM、XRD和FT-IR研究并分析了聚丙烯酸钠在矿化过程中对晶体生长的调控作用. 研究发现, 与未添加有机分子相比, 聚丙烯酸钠的存在显著降低了仿生矿化层中低结晶度碳酸羟基磷灰石晶体的尺寸, 同时改变了晶体的几何形态并增加了矿化层的致密度.

Abstract: Microarc oxidation (MAO) technique was applied for the formation of ceramic coating on titanium surfaces, and the modulating mechanism of sodium polyacrylate to crystal growth was studied by SEM, XRD and FT-IR in the biomineralization. Results show that the crystal size of HCA is reduced when specimen is bio-mineralized with the addition of sodium polyacrylate. Meanwhile, the morphology of crystal is changed and the density of mineralization layer is increased when sodium polyacrylate is applied.

Key words: organic macromolecule, modulation, biomineralization, microarc oxidation
