摘要/Abstract

摘要： 　应用沉淀法合成纳米羟基磷灰石,并以电泳沉积法在粗糙化的钛表面制备纳米结构的羟基磷灰石涂层.纳米涂层有利于保持羟基磷灰石的化学组成和结构,制备的涂层均匀并且无裂缝,烧结后涂层仍保持纳米结构,其烧结温度也明显降低。钛表面经化学处理后,可形成很多微孔和TiO2薄层,增强了涂层和基体之间的结合.涂层的结合力为 18±2. 5MPa,硬度和杨式模量分别为 32. 0和 2. 4GPa.

Abstract: A hydroxyapatite coating with nano-structure on the roughened titanium surface was prepared by electrophoretic deposition process. To decrease sintering temperature the HAp nanoparticles synthesizedby a wet chemical method was used. It is observed that the coating is uniform without cracks. After sintering the nano-strueture of HAp coating remains unchanged. The surface treatment of Ti is applied to form a distribution of small pits and TiO_2thin layer that improve the adhesion of coatingto Ti substrate. It is shown that the bonding strength of coating is as high as 18±2.5MPa. The hardness and Young's modulus are 40.6 and 0.42 GPa, respectively.
