Studies on Prepavation and Properties of Film Caleium Puosphate Materials

用ESCA、IR和x射线衍射等手段研究了电泳和溅射法制备的陶瓷和金属用磷酸盐涂层。在钛板上电泳形成羟基磷灰石薄膜时，发现醇类与酰胺类的混合物和醇类与二甲硫氧化物的混合物是最合适的分散介质。在这些混合溶剂中，钛板上的薄膜数量比在各自的纯溶剂中显著增加。以磷酸钙玻璃（CaO/P_2 O_5= 55/45）为靶材，采用溅射法制备了钛板上的无定形正磷酸钙。用红外光谱法检测了薄膜中少量的浓缩磷酸盐。链状磷酸盐在溅射过程中被部分分解。溅射膜中的磷酸盐含量比靶玻璃中的磷酸盐含量要小。

Phosphate film of coating for ceramics and metals by electrophoresis and sputtering was studied by means of ESCA, IR and X-ray diffraction. On the electrophretic formation of hydroxyapatite film on Ti plate the mixture of alcohols and amides and the mixture of a alcohols and dimethlsuphoxide were found to be most appropriate dispersion medium. The amounts of films on Ti plate in those mixtures increased remarkably compared with those in the respective pure solvents. Amorphous calcium orthophosphate on Ti plate was obtained by sputtering, using calcium phosphate glass (CaO/P_2 O_5= 55/45) as a target. A small amount of condensed phosphates in films was detected by IR. Chain phosphates were partially decomposed during the sputtering. The phosphate content in the sputtered films was smaller than that of the target glass.
