The focus of the paper is the wear behavior of hybrid aluminum metal matrix composites. The main objective of the investigation is to conduct the wear test at room temperature for both the as-cast and age hardening conditions. Materials chosen for the study are Aluminum 7075 as a matrix, Silicon Carbide and Alumina are the reinforcements. Hybrid metal matrix composites are produced by utilizing stir casting route for 5-15 wt.% silicon carbide and alumina. Microstructural characterization of hybrid aluminum metal matrix composites reveals the homogeneous mixing of reinforcements. It is noticed that the higher composite hardness is obtained due to the raise in weight percentage of the reinforcement up to 10% of hybrid reinforcements. In the T6 heat treatment, there is a gain in hardness by 24 % for optimum percentage of reinforcement i.e. 10 % compare with as-cast composites.

“…The Al slabs were melted in the furnace. In the wake of liquefying, liquid Al was superheated to 750 C. 5 The required measures of SiC/Al 2 O 3 particles were added to the liquid Al while mixing with a stirrer at 600 r min À1 . The liquid Al7075-SiC/Al 2 O 3 was filled in a permanent mold and allowed to set.…”

In the present investigation, wear test is conducted on a pin-on-disc device at room temperature for both the age hardening and without age hardening conditions. Al7075 has been chosen as the matrix material. Hybrid aluminum metal matrix composites are produced utilizing stir casting route for enhancing the wear behavior and hardness number. The reinforcement used is silicon carbide with 5, 10, and 15 wt% and alumina as the reinforcement in 5, 10, and 15 wt%. In the aluminum matrix, microstructural characterization reveals homogeneous mixing of reinforcements. This investigation shows that the enhanced wear resistance is due to the increment weight fraction of reinforcement. By raising the sliding speeds, there is a reduction in the rate of wear and it reduces with increment in the sliding distance. With increasing weight fraction, there is decrement in the rate of wear of composites. In general, tribological property enhances because of the addition of the two reinforcements.

Composite materials are basically applied to the structures, bridges, operational parts and buildings, such composites from the pure metals. ex: aluminum, which have less hardness comparatively and good tensile properties. In order to minimize and overcome this problem, in general, different materials at various percentages to the pure metals were added and their properties have been investigated. Thus, better hardness can be achieved in earlier studies. But, in this study, The materials like aluminum (7075-T6), the glass powder and the resin of different sizes are taken for making and preparation of the composite materials. Aluminum, used as a base metal and by varying the percentages of the known additives, a composite can be made and thus, to the made specimen material properties have been studied.
