摘要

采用电化学沉积法在医用Mg-Nd-Zn-Zr合金表面沉积含氟羟基磷灰石（FHA）涂层

研究了电解液pH值对FHA涂层形成的影响。结果表明

电解液pH值在3.0～4.0范围内

随着pH值的升高

离子浓度逐渐增加

促进了FHA的形核

FHA形貌由针状转变为带状

其平均长度也由5μm增长至11μm;当pH值进一步升高至5.0时

OH-离子浓度进一步增加

引发Ca和P离子沉淀

不利于FHA的形核

其形貌由带状逐渐向细小的球状转变

球状FHA的直径范围为0.2～0.3μm。

Abstract

Fluorinated hydroxyapatite（FHA）coating was deposited on the surface of medical Mg-Nd-Zn-Zr alloy by electrochemical deposition.The effects of electrolyte pH value on the formation of the FHA coatings were investigated.The results reveal that the concentration of OH

is increased with increasing pH value from 3 to 4

which promotes the nucleation of FHA.The morphology of FHA is converted from needle to band structure.And the average length of the FHA is increased from 3μm to 10μm.The concentration of OH-is further increased when the pH value of electrolyte further is increased to 5

resulting in the precipitation of calcium and phosphorus ion from the electrolyte

so inhibiting the formation process of FHA.The morphology of FHA is gradually transformed from strip structure to fine spherical structure

where the diameter of spherical-shaped FHA is in range of 0.2μm to 0.4μm.
