Development of new apatite coating method as dental implant material

对磷灰石进行了LPD（液相沉积）镀膜的基本检查。结果得出如下结论：1。适宜的钙离子与磷酸盐离子的摩尔密度比为1.7.2。适用于不锈钢、钛、石英、氧化铝等材料表面涂有磷灰石的器皿。用氢氧化钠溶液对基材进行预处理，预处理后用纯净水和超声波乙醇洗涤。以亚氨基二乙酸为干燥剂。通过x射线衍射和红外吸收光谱测量沉积产物，发现磷灰石表面化合物中含有缺钙碳酸盐。提取到材料上的薄膜强度不足。经热处理后，磷灰石的结晶过程加快，薄膜强度提高。

The basic examination apatite coated by the LPD (Liquid Phase Deposition) method was done. As a result, the following finding was obtained.1. The mole ratio of the density of a suitable calcium ion and phosphate ion of the dipping solution was 1.7.2. Stainless steel, titanium, quartz and alumina ware suitable for ware of material coated with the apatite.3. The pretreatment of the substrate process with the sodium hydroxide solution, and after is washing with purified water and ethanol by ultrasonication.4. Iminodiacetic acid was used as clelating agent.5. Surface compounds were found calcium deficient apatite containing carbonate, by x-ray diffraction and infrared absorption spectrum measurement deposition product.6. As for the thin film extracted to the material, strength was insufficient. Then for heat-treated, the crystallization of apatite progresses and strength of a thin film has increased.
