| Abstract | ||||
| Metal matrix composites reinforced by carbon nanotubes as well as the effect of Nano Al2O3 (n- Al2O3) particles and carbon nanotubes (CNTs) are very promising materials, suitable for a large number of applications. These composites consist of a metal matrix filled with Nano-particles featuring physical and mechanical properties very different from those of the matrix. The Nano-particles can improve the base material in terms of electrical properties, damping properties and mechanical strength. In this work we investigated the effect of reinforcing Al-2024 with CNTs and n- Al2O3. The Al-2024 alloy was produced by powder metallurgy. The alloy strengthened by a dispersion of two weights % CNTs, 2wt% n- Al2O3, and 1weight % CNTs + 1wt% n- Al2O3 respectively. The effect of the CNTs, and Nano Al2O3 on the microstructure, hardness, and wear, were studied. The micro structural results showed a homogeneous dispersion of CNTs and n- Al2O3 into Al2024. We obtained that the composite 1weight % CNTs + 1wt% n- Al2O3 can increase, hardness as well as reduce the weight loss by 46%, and 80%, respectively. Our results enhance the wear behavior of the composites by using different types of reinforcements. | ||||
