摘要

采用微弧氧化法在不同电解质浓度的钙磷电解液体系中制备了纯钛生物钙磷陶瓷膜。借助SEM、三维视频显微镜分析了膜层表面形貌。研究了电解液钙磷比一定条件下

电解质组成浓度与膜层三维形貌、孔隙率、孔隙密度、孔径尺寸的关系。结果表明

随着电解质浓度增加

陶瓷膜厚度增加

孔隙率、孔径尺寸下降

孔隙密度也呈下降趋势;在低浓度时

陶瓷膜表面多为火山口状多孔结构

在浓度较高时

多为熔融物反复作用形成的多孔结构;NaOH浓度的改变对于陶瓷膜表面影响比较大。

Abstract

A biomedical Ca/P film on pure Ti was prepared by micro-arc oxidation in the Ca/P electrolyte systems with different concentration.The surface micro-topography and 3-D morphology were observed by SEM and HIROX.The relationship of porosity ratio

density

size and 3-D morphology with electrolyte concentration was investigated under the condition of the given Ca/P ratio electrolyte.The results show that with the electrolyte concentration increase

the thickness is increased and the porosity ratio

pore size as well as pore density are decreased.In low concentration

the surface of the film exhibits more crater-like porous structure

however

in high concentration

the porous structure is formed by the sintering process of melt repeatedly.Effects of NaOH concentration on the ceramic film is more important.
