Abstract:

由机械合金化法(MA)制得纳米级Al2O3颗粒弥散镶嵌于微米级Cu颗粒表面的复合粉末,利用球形化工艺改善所制得复合粉的形貌及粒度范围,分别采用热压法(HP)和放电等离子体烧结(SPS)法制备Al2O3/Cu复合材料。通过测试密度、电导率、抗弯强度及SEM复合粉形貌和烧结体断口分析、微区成分分析,对比研究了Al2O3质量分数分别为0%、0.5%、1.0%、1.5%时Al2O3/Cu复合材料的物理、力学和电学性能。结果表明:不同制备工艺下随着Al2O3含量增加,材料的抗弯强度先增后降,电导率除受杂质影响外,还受材料缺陷的影响,故变化规律不明显,对于Al2O3含量相同的Al2O3/Cu复合材料,采用SPS法制备的复合材料的致密度、抗弯强度及电导率均高于HP法;在弯曲应力下两种制备方法所得复合材料均发生延性断裂。
