Aluminum metal matrix composites (AMMCs) have significant applications in aviation, auto and military, because of their high solidarity to wear proportion, resolution, light weight, great wear resistance and improved thermal properties. Artistic particles, for example, Al2O3, SiC, TiC, B4C and NbC are the most generally utilized materials for strengthening aluminum. In this paper the proposed work is to investigate the effect of reinforcement on microstructure and wear properties of Al7475/ NbC Metal Matrix Composites by possessing the composites using liquid metallurgical technique by varying the weight percentage (wt.%) of reinforcement Niobium Carbide (NbC) from 2 to 8% by an interval of 2wt%. The obtained results show the uniform distribution of reinforcements without the formation of clusters in the matrix material and also it is observed that the increase in weight percentage of reinforcement significantly decreases the wear rate. |
