An Effect on Wear Characteristics of Nano-AL2O3 Particulates Reinforced AL7075 Metal Matrix Composite

Aluminium alloy are playing a major role in synthesizing the body parts of aerospace and automobile sector, because of its ease of production and adoptable to the modification. The hard ceramic particulates addition into the aluminium matrix will enhance the strength with respect to weight ratio and correspondingly the hardness and wear rates are getting improved both at room temperature and at elevated temperature. In this view the present work deals with the synthesis of the aluminium matrix composite reinforced with Nano-Al2O3 particulates at different weight percentages via liquid metallurgy method. The composite is prepared in a confined environment to maintain the homogeneous distribution of the Nano particulates over the matrix. Further the characterization of the prepared composite was carried out using SEM and XRD. Study of wear rate has been conducted by considering parameters like varying load, speed and distance. Significant results are obtained with the wear rate and worn surface study along with the homogeneous distribution of the Nano particulates over the matrix.
