采用一种新的溶液法在多孔氧化铝基体上成功地制备了羟基磷灰石（HA）薄膜。涂层HA通过具有中间热膨胀系数的玻璃烧结助剂与基材牢固结合。涂层也被发现是微观结构和化学均匀的基质中的互连孔的表面上。力学性能测试结果表明，HA涂层的复合材料的强度显着提高，表明在硬组织修复的结构骨替代物的高潜力。
A thin film of hydroxyapatite (HA) was successfully coated onto a highly porous substrate of alumina by using a novel solution technique. The coated HA bonded strongly to the substrate through a glass sintering aid with an intermediate thermal expansion coefficient. The coating was also found to be microstructurally and chemically uniform on the surfaces of the interconnected pores in the matrix of the substrate. Mechanical property testing results showed that the strength of the HA-coated composite was significantly improved, indicating a high potential for structural bone substitutes in hard tissue prosthetics.
