Aluminium hybrid composites are the new groupof metal matrix composites (MMCs) due to their attractive properties like high ductility, high conductivity, light weight and high strength to weight ratio and ever-increasing demand of these super material in the field of aircrafts, automobile, marineapplications. Carbon Nanotube (CNTs) are also known for their high strength, stiffness and their low density. Graphene also has attracted considerable attention in the last several years because of its excellent properties such as high mechanical strength, modulus, high electrical, high thermal conductivity and optical transmittance, which when combined together makes CNTs and graphene both were an ideal reinforcement to metal matrix composites. In the present research work, the dry sliding wear behavior of aluminum matrix nanocomposites containing various amounts of graphene (0.5 and 1wt.%) particles and fixed percentage of carbon nanotubes (2 wt.%) coated/un-coatedwas investigated. The specimens were prepared by mechanical milling of Aluminium 6061 (AA6061) and Multi walled Carbon Nano Tubes (MWCNTs) and graphene nanocomposite powders, followed by pressing. Wear tests were carried out at room temperature using pin-on-disc machine under variable normal loads. Wear mechanisms are discussed based on scanning electron microscopy image observations of wear tracks and wear debris morphology.
