Wear Characteristics of Aluminum Composite Reinforced by Multiwall Carbon Nanotubes

Nanoaluminum composites are finding a large area of application in aerospace, marine, and automotive industries. They have been proven as a suitable candidate for replacing iron and its alloy in these industries because of their good strength-to-weight ratio and other enhanced properties. Carbon nanotubes are in the eye of many researchers and scientists for fabricating nanocomposites because of their marvelous mechanical, electrical, tribological, and thermal properties. Many researchers have fabricated Al-CNT composite through different solid and liquid processing, and they have demonstrated this composite suitable for functional and structural industrial solicitations. This paper represents the synthesis of Al-CNT composites through stir casting technique to study their wear behavior. Composites were prepared by reinforcing different ratios of multiwall carbon nanotubes in Al matrix. Outcome of the study and investigations revealed that the composite containing 0.2 wt%CNT showed the best result with approximately 7% improvement in wear resistance.
