摘要

采用混合盐反应（MixedSaltReaction）原位合成法成功制备了TiB2/2014Al复合材料

并对其摩擦磨损性能进行了研究。采用X射线衍射分析物相和扫描、透射电镜观察了其微观组织。结果表明

原位生成的TiB2颗粒非常细小

尺寸小于1μm

内生TiB2颗粒分布均匀

明显细化了复合材料组织。室温干滑动摩擦磨损试验表明

复合材料耐磨性高于基体合金

基体合金磨损机制以粘着磨损为主

复合材料的磨损机制为典型的磨粒磨损。

Abstract

2014Al/TiB2 composites were fabricated by a mixed salt reaction in-situ synthesis process

and friction and wear properties of the composites were investigated.Microstructure of the composites was observed by XRD（X-ray diffraction）

SEM（scanning electronic microscope） and TEM（transmission electronic microscope）.The results reveal that in-situ TiB2 particle is very fine with grain size smaller than 1μm and uniform distribution in the composites

obviously refining the microstructure of the composites.Dry sliding frictional and wear experiment at room temperature show that wear resistance of the composites is evidently superior to that of matrix alloy.Wear mechanism of matrix alloy is characterized by adhesive wear

and wear mechanism of the composites is characterized by typical abrasive wear.
