In recent days, the scope for particle reinforced metal matrix composites manufactured through powder metallurgy process has been intensified due to its remarkable blend of properties. Specifically, the enhanced tribological properties of metal matrix composites (MMCs) have paved way for using them in various fields including automotive, aerospace and other numerous applications. The processing methods of such MMCs are the becoming more challenging when considering smaller (nano range) particle as a reinforcement which requires advanced processing techniques. Carbon allotropes including graphene and CNT exist in nano-range are the unique material which are used to enhance various properties of nanocomposites. However, development of such materials is in initial stage due to lack of processing technique for specific applications. This needs to be channelized through integration of fabrication method along with the reinforcement selection and adding methods to meet the industrial demands. The processing technique and interfacial bonding of the matrix and reinforcement materials will define the final property of the component. This chapter focuses on the development of the composites and the evaluation of different Graphene/SWCNT/MWCNT addition on the tribological properties, interfaces between the matrixes, reinforcement and sliding plate, microwear mechanism of developed nanocomposites. © 2020 Elsevier Ltd.
