Mechanical and wear characteristics of (Al7075/SiC/Gr/Zr) hybrid metal matrix composites using ultrasonic assisted stir casting process

Abstract

Al 7075 alloys are important in many technological domains, including the aerospace and automotive industries, on account of their exceptional strengthto-weight ratio and some other tribological and mechanical properties. Under dry and lubricated conditions, Al7075 alloys have poor sliding wear resistance performance. There are several available classes of a few alloys, however, the Al7075 alloy, which is found in a number of elements, exhibits good mechanical qualities that are being developed and researched for use in tribology. *Author for correspondenceAs ceramic particles are added, friction and wear resistance are also improved, which boosts the performance of ceramic-based composites. Aluminum alloy SiC/Gr/Zr filled composites are being investigated in order to improve their wear characteristics. Amith and Lakshmanan [1] utilized ultrasonic assisted stir casting process for the formation of hexagonal boron nitride (h-BN)/Al7075 metal matrix composite. The objective is to enhance the physical properties of the hybrid composite metal than the base matrix. Tensile test was conducted on top of h-BN/Al7075 composite and concluded that 29.46% enhanced in tensile strength and stated only 0.6% is a correct composition. Kumar et al. [2]
