摘要

以无水乙醇为球磨助剂

采用机械球磨方法制备了纳米羟基磷灰石-钛（nHA-Ti）复合粉末。利用X射线衍射（XRD）、扫描电子显微镜（SEM）和能谱分析仪（EDS）

研究了球磨过程中（5

0h）复合粉末的相组成和微观组织;通过电子探针（EPMA）对Ca元素面扫描

分析了球磨过程中复合粉末的均匀化效果。结果表明

随着球磨时间的延长

复合粉末逐渐细化和均匀化

球磨30h可使复合粉末形成nHA弥散分布在Ti大颗粒上的包覆状粉末结构

且复合粉末中nHA获得了较好的均匀化效果。

Abstract

Nano-hydroxyapatite-titanium（nHA-Ti）composite powder was prepared by mechanical milling in alcohol media.Phase constituent and microstructure of the composite powder during mechanical milling have been observed by XRD（X-ray diffusion）

SEM（scanning electron microscope）and EDS（X-ray energy dispersive spectrometer）

and homogeneity of the composite powder has been analyzed by EPMA（electron probe X-Ray microanalysis）.The results show that the powders of Ti/HA are fined to a nano-scale with increasing in milling time.The nano-composite powders with fine structure has been prepared

in which the nHA particles embedded in the larger Ti particle

after milling for 30 min with the wet-milling.Furthermore

it can be found that the nHA would be distributed more homogeneously.
