摘要
用搅拌摩擦加工(FSP)技术将多壁碳纳米管(MWCNTs)添加在LC9铝合金板表面,并在其表层形成碳纳米管铝基复合材料,表面强化高强铝合金材料。结果表明,MWCNTs的加入,可使铝基复合材料的耐磨性明显提高。随着MWCNTs含量的增加,复合材料的磨损量呈降低趋势,耐磨性能提高。在复合材料表面主要发生了磨粒磨损现象。
Friction stir processing （FSP） was employed for the A1 matrix composite surface layer on LC9 high-strength aluminum alloy, and formed carbon nano-tubes-aluminum max composite in the surface, surface strengthen high strength aluminum alloy. The results show that the wear properties of the aluminum alloy LC9 are better than the base metal after filled MWCNTs. As the amount of MWCNTs increase, the wear properties enhances. In the surface of max composite the particle attrition phenomenon mainly happened.
