Although carbon nanotube (CNT) is a promising material due to its excellent mechanical and functional properties, CNT has not been effectively used for high performance composites due to the degradation of its mechanical properties as a result of insufficient dispersibility of CNT in its matrix. In this study, CNT/aluminum (Al) matrix functionally graded materials (FGMs) were fabricated by centrifugal slurry methods. The dispersion of CNT was carried out with the solvent of dimethylacetamide (DMAs), and the dispersant of potassium carbonate (K2CO3) under ultrasonic sonication conditions. Tribological characteristics on the FGMs were investigated using a ball-on-disk tribometer. It was demonstrated that the presence of CNT contributed to an increase of the coefficients of friction and an enhancement of wear resistances.

Carbon nanotube (CNT) has received broad scientific and industrial attention due to their excellent mechanical and functional properties. However, CNT has not been effectively used for high performance composites because of degradation of mechanical properties due to insufficient dispersibility of CNT in the matrix. In this study, CNT/ aluminum (Al) matrix functionally graded materials (FGMs) have been focused on. The processes of dispersion of CNT have been carried out with the solvent of dimethylacetamide, and the dispersing agent of potassium carbonate, which is an inorganic salt, under ultrasonic sonication conditions. Centrifugal slurry methods have been applied to obtain gradient of content of CNT in CNT/ Al matrix FGMs. Tribological characteristics on CNT/ Al matrix FGMs have been investigated using a ball-on-disk tribometer. It has been demonstrated that CNT contributes to enhance wear resistances.
