“…Interestingly, the CNTs apparently aid super-plastic forming of the composite material, an advantage attributed to inhibited matrix grain growth and grain boundary lubrication 45 . Related studies of the preparation of CNTs/alumina composites using the in situ method have been performed by An et al 49 & Lim et al 50 . As discussed further below, the tribological properties were significantly improved by the presence of CNTs at the alumina grain boundaries (see Figure 3 (b)) 49 .…”

Due to the remarkable physical and mechanical properties of individual, perfect carbon nanotubes (CNTs), they are considered to be one of the most promising new reinforcements for structural composites. Their impressive electrical and thermal properties also suggest opportunities for multifunctional applications. In the context of inorganic matrix composites, researchers have particularly focussed on CNTs as toughening elements to overcome the intrinsic brittleness of the ceramic or glass material. Although there are now a number of studies published in the literature, these inorganic systems have received much less attention than CNT/polymer matrix composites. This paper reviews the current status of the research and development of CNT-loaded ceramic matrix composite materials. It includes a summary of the key issues related to the optimisation of CNT-based composites, with particular reference to brittle matrices and provides an overview of the processing techniques developed to 2 optimise dispersion quality, interfaces and density. The properties of the various composite systems are discussed, with an emphasis on toughness; a comprehensive comparative summary is provided, together with a discussion of the possible toughening mechanism that may operate. Lastly, a range of potential applications are discussed, concluding with a discussion of the scope for future developments in the field.3

“…The heating rate was fixed for 100 °C/min. Alumina-CNT composite powders were synthesized in the catalytic decomposition of acetylene over alumina powders impregnated with iron catalysts by An et al, 2003. The alumina, MgO, and Fe(NO 3 ) 3 •9H 2 O powder were mixed by planetary ball milling to prepare the alumina powder impregnated with iron catalysts.…”

The main wear mechanism in the nanocomposite was abrasion of the ceramic and carbon components which act in the interface as a sort of lubricating media. The experimental results demonstrate that the addition of CNFs to the ceramic composites significantly reduces friction coefficient and wear rate, resulting in suitable materials for unlubricated tribological applications.
