碳纳米管（CNTs）由于其优异的力学和电学性能，近年来作为材料的增强体受到了广泛的关注。然而，陶瓷-碳纳米管复合材料的研究很少有报道。采用热压法制备了氧化铝-碳纳米管复合材料，研究了碳纳米管的加入对复合材料力学性能和摩擦学性能的影响。采用硝酸铁浸渍氧化铝催化裂解乙炔气制备了氧化铝-碳纳米管复合粉体。硝酸铁的含量控制在0 ~ 0.5mol.%以改变氧化铝-CNT复合物中的CNT组成。研究了热压复合材料的微观结构和力学性能，以解释碳纳米管组成对碳纳米管复合材料增强氧化铝摩擦学性能的影响。(C)2003 Elsevier Science B. V.保留所有权利。
Carbon nanotubes (CNTs) have lately attracted remarkable attention as reinforcements of materials because of their exceptional mechanical and electronic properties. However, studies on the ceramic-CNT composite have been rarely reported. Alumina-CNT composites have been produced to investigate the effect of carbon nanotube addition on the mechanical and tribological properties by hot-pressing. The alumina-CNT composite powder was prepared by catalytic pyrolysis of acetylene gas with an iron nitrate impregnated alumina. The contents of iron nitrate were controlled from 0 to 0.5 mol.% to change the CNT compositions in the alumina-CNT composite. The microstructures and mechanical properties of hot-pressed composites have been investigated to explain the effect of the CNT compositions on the tribological properties of the alumina reinforced with CNT composites.
