【 摘 要 】
Being limitation of heavy density and corrosion resistance imposed by ferrous materials, nonferrous material come into existence especially aluminium and its alloys. Among aluminium alloys, Aluminium A356 has gained wide attention because of its excellent fluidity. Because of superior mechanical property of composites, number of investigations was carried out using different reinforcements like SiC, B4C, TiB2 and Al2O3. Nano particles are well mixable with corresponding matrix while processing metal matrix composite using stir casting technique. Most of the work has been carried out using aluminium A356 alloy as matrix with different reinforcements using stir casting processing route with an intention for automobile applications. But scanty of literature is available in the domain of processing hybrid composite. Thus, in the present investigation an attempt has been made to process A356 aluminium alloy as matrix materia l along with SiC and Al2O3 as reinforcement with an end application of brake shoe pads in which wear resistance is one of the main criteria. Among all the three processed (composite and other two hybrid composite), hybrid composite having 2% SiC and 1% Al2O3exhibited maximum hardness and offers maximum wear resistance and it may be attributed to mixed mode of both abrasive and adhesive mechanism. Hence, this hybrid composite is recommended for brake shoe application.
