Using carbon nanotubes (CNTs) as reinforced phase, it was made to carbon nanotubes/Magnesium matrix composite by the foundry method in Argon gas protection. The experiment results show that CNTs can strengthen the mechanical properties of the CNTs/Magnesium matrix composite, and tensile strength and elongation ratio are greatly improved. Furthermore, the plating CNTs are better than un-plating CNTs in strengthening effects. Additionally the quantity of CNTs can not be too great, or the properties will be descended to a great extent without distraction of CNTs. Tensile strength has been higher by 150 % and the elongation ratio is higher by 30 % than matrix’s at best, and the fracture of the composite sample has a character of dimples.

Powder Metallurgy Process

Magnesium matrix composite reinforced by carbon nanotubes (CNTs)-Al2O3 hybrid reinforcements was successfully fabricated by a novel process. CNTs-Al2O3 in-situ mixture was synthesized by directly growing CNTs on Al2O3 particles acting as the carrier of Ni catalysts via chemical vapour deposition. The influences of Ni catalyst content on the morphology, structure and yield of CNTs were investigated. By powder metallurgy process, the CNTs-Al2O3 in-situ mixture was dispersed in Mg powder to fabricate the CNTs-Al2O3 synergistically reinforced Mg matrix composite. The performance test results showed that, the Mg matrix composite possessed improved mechanical properties, and the strengthening effects of CNTs-Al2O3 in-situ mixture were prior to those of single CNTs or Al2O3 reinforcement. The improvement of mechanical properties was due to that the introduction of Al2O3 can promote the dispersion of CNTs in Mg matrix and improve the interfacial bonding between CNTs and Mg.
