Carbon nanotubes (CNTs) reinforced Al matrix composites were prepared by friction stir processing (FSP). The effect of CNTs content on the wearing performance and hardness of Al matrix composites was studied. Results show that CNTs reinforced Al matrix composites by FSP are to create a good dispersion of the CNTs in the matrix and to achieve a good combination with the matrix. The interface of CNTs and pure aluminum matrix is smooth, no defects and is one kind of mechanical bonding interface. There are a large number of dislocations. CNTs can strengthen the matrix composites effectively and obviously improve the hardness of the composites. With increasing CNTs content, CNTs can also improve the wear performance of the matrix composites.

In this paper, a colloidal processing route was adopted to disperse multi-walled carbon nanotubes (MWNTs) into alumina powders homogenously. Alumina matrix composites containing 0.1 to 2 weight percent of MWNTs were successfully fabricated by pressureless sintering. Also, 1wt% MWNTs-alumina composites were prepared by hot pressing for comparison. It was found that when the sample was sintered at 1450oC, the addition of 1wt% carbon nanotubes led to 10% increase in bending strength compared with monolithic alumina. The reinforcement mechanism was discussed based on the microstructure investigation. The broken nanotubes and pullout of MWNTs at interfaces are efficient in transferring the load from the alumina matrix to the nanotubes, leading to the improvement of the mechanical properties.
