The mechanism of apatite deposition on chemically treated Ti surfaces still is being studied. In this study, simulated body fluid, calcium aqueous solution, phosphate aqueous solution, and accelerated calcification solution are used as media to investigate the order of calcium and phosphate ion deposition on chemically treated Ti surfaces. The results of inductively coupled plasma spectra, scanning electron microscopy, and energy dispersive X-ray analysis show that calcium deposition is the prerequisite for phosphate ion deposition.
磷灰石在化学处理钛表面的沉积机制仍在研究中。在本研究中,使用模拟体液、钙水溶液、磷酸盐水溶液和加速钙化溶液作为介质,研究钙和磷酸根离子在化学处理钛表面的沉积顺序。电感耦合等离子体光谱、扫描电子显微镜和能量色散X射线分析结果表明,钙的沉积是磷酸根离子沉积的先决条件。
