Development of new apatite coating method as dental implant material

对液相沉积法制备的磷灰石涂层进行了初步的研究。结果，得出以下结论：1.浸渍溶液的适当钙离子和磷酸根离子的密度的摩尔比为1.7.2。不锈钢、钛、石英、氧化铝器皿适用于镀有磷灰石的材料器皿.用氢氧化钠溶液对底物进行预处理，然后用纯化水和乙醇超声清洗.采用亚氨基二乙酸作为澄清剂.通过x射线衍射和红外吸收光谱测定沉积产物，发现表面化合物为含碳酸盐的缺钙磷灰石.至于提取到材料的薄膜，强度不足。然后，对于热处理，磷灰石的结晶化进行，并且薄膜的强度增加。

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.
