Abstract
Studies show that monolithic Al lacks requisite properties required for industrial applications. However, these properties can be enhanced by the addition of high-performing reinforcement such as carbon nanotubes (CNTs). Here, Al is reinforced with CNTs and consolidated via spark plasma sintering, with the aims of improving its tribology, thermal and electrical properties. The tribological test was conducted on a ball-on-disc tribometer. The thermal test was done with the thermogravimetric analyzer and laser flasher apparatus; the electrical conductivity test was carried out with four-point probe meter. Results obtained showed that 4 wt% of CNTs improved the COF of Al alloy by 52% and wear volume by 23%. It also improved the thermal conductivity by 35%. The electrical result showed a marginal improvement of 2% with Al-8CNTs. Therefore, the improvements in tribology and thermal properties without compromising electrical conductivity show that Al-CNTs are a robust material for industrial application especially in high-transmission conductor.
