Wear behavior of Al 7075/Al2O3/SiC Hybrid NMMC’s by Stir Casting Method

Abstract

Hybrid Metal Matrix Nano Composites (HMMNCs) are obtaining large applications in aerospace, marine, defense, and automobile markets due to their high stiffness, high strength-to-volume portion, deterioration resistance, and exceptional wear resistance. Nanohybrid materials are typically selected for engineering applications since they have a correct organization of mechanical qualities. Today enhancement of nanohybrid composites has transformed into a substantial area of a research study in materials and manufacturing science. In my research study, the AA 7075 improved with 1.0, 2.0, 3.0 and 4.0 wt. % of nano- Al 2 O 3 (20-30nm), Nano SiC (50nm) and also 1 wt. % of Mg (micro) to make the hybrid metal matrix composite. The existing research is concentrated on establishing the physical and mechanical characteristics of Aluminium 7075 in the presence of nano -Al 2 O 3 and Nano silicon carbide in the melt. The reinforcement fragments boosted from 1 to 4 Wt. % and stir casting approach are executed for the production of Al-based metal matrix nanocomposites. The tribological behavior of nanocomposites such as Friction coefficient, wear resistance, wear rate and weight-loss examination are assessed using a pin on disc apparatus. Wear properties like wear rate and friction coefficient of AA7075 minimizes the increase of Al 2 O 3 and SiC powder.
