| 摘 要： | 采用机械合金化技术制备高分散多壁碳纳米管(MWCNTs)-铝(Al)复合材料。将纯度99%的铝粉和质量分数2%的MWCNTs经超声和水平球磨处理使Al颗粒与MWCNTs间产生机械键合力。场发射SEM观察表明,MWCNTs分散在Al薄片的表面,随球磨时间的不同,颗粒大小和形貌各异。采用加压烧结手段将混合粉末加工成块体材料,其微观硬度测试表明,加入MWCNTs后Al基体的机械性能得到提高。

| Abstract: | Mechanical alloying was used to disperse multiwall carbon nanotubes(MWCNTs) in an aluminum(Al) matrix.Mixtures consisting of 99% pure Al powder and a mass fraction of 2% MWCNTs were sonicated.Then,horizontal ball milling was used to generate mechanical bonding between the Al particles and the MWCNTs.The structure observed by a field-emission scanning electron microscope revealed an attachment of MWCNTs to the surface of the Al-flakes.FESEM results showed that particle size and morphology varied with milling time.Finally,the composite powders were processed into bulk material by compaction and sintering.The macro-hardness confirmed the improvement in the mechanical properties due to the addition of MWCNTs to the Al matrix. |
