摘要: 采用光学显微镜与超景深显微镜观察了不同Al2O3添加量的Al2O3增强Al70Fe10Cu20合金微观组织，利用X射线衍射仪、拉伸试验机、维氏硬度计、摩擦磨损试验机、密度计、电导率仪检测了Al2O3增强Al70Fe10Cu20合金力学性能、摩擦磨损性能、密度与电导率。结果表明，Al2O3颗粒的添加量以及真空熔炼后Al2O3颗粒在Al70Fe10Cu20合金中的分布均匀性对复合材料的显微组织和性能影响较大。综合各项性能指标得出Al2O3最优添加量为0.1 wt%，与不添加Al2O3的Al70Fe10Cu20合金相比添加0.1 wt% Al2O3的Al70Fe10Cu20复合材料的密度和电导率降低幅度很小，而硬度、抗压强度以及耐磨性却有显著提升。
Abstract: The microstructure of Al2O3 reinforced Al70Fe10Cu20 alloy with different Al2O3 additions was observed by optical microscope and super depth of field microscope. The mechanical properties, friction and wear properties, density and conductivity of Al2O3 reinforced Al70Fe10Cu20 alloy were detected by X-ray diffractometer, tensile testing machine, Vickers hardness tester, friction and wear testing machine, density meter and conductivity meter. The results show that the addition amount of Al2O3 particles and the distribution uniformity of Al2O3 particles in Al70Fe10Cu20 alloy after vacuum melting have a great influence on the microstructure and properties of the composite material. The optimal addition amount of Al2O3 is 0.1 wt% based on various performance indicators. Compared with Al70Fe10Cu20 alloy without Al2O3, the density and conductivity reduction of Al70Fe10Cu20 composite material with 0.1 wt% Al2O3 was very small, while the hardness, compressive strength and wear resistance were significantly improved.
