| description | In this paper the combined effect of alumina and graphene reinforced with aluminum matrix by using stir casting methodology, was evaluated. Hybrid metal matrix composites gives combined results effect of different reinforced aspects when combined with ductile matrix appearance. Both alumina and graphene we are varied by the weight proportions in order to 1%, 2% and 3% respectively. With increase in the weight percentage the mechanical properties like hardness were increased. Density was reduced. The detailed microstructure evaluation shows the mixing of reinforcement in the matrix. The tribological behaviour of hybrid composite was determined. The graphene agglomeration in the composite increased the hardness by 35% as compared to the base material. The composite
reinforced with 3% alumina + 3% graphene recorded highest hardness. |
