Mechanical Properties and Wear Characteristic of (Aluminum-Zinc Oxide) Metal Matrix Composite Prepared Using Stir Casting Process

Abstract

The developing of Composites Metallic Matrix for Aluminum (AMMCs) is one of the leading engineering applications requirements because of the excellent mechanical characteristics low weight with high strength for this metal. This research investigated the impact of ZnO particles on the Compressive strength, Hardness, and Wear characteristics of Al metallic matrix composite manufactured by method stir casting. The strengthening added different weight percent (0, 2, 4, 6, 8 and 10) % ZnO. The microstructure of specimens is the analysis by an optical microscope and determines the compressive strength, hardness, and wear characteristics which increase with an increased weight percentage of ZnO. The increase in the percent of Brinell hardness is (15%), (25%), (35%), (40%), and (50%) for aluminium reinforced with 2, 4, 6, 8, 10 wt. % ZnO particles specimens respectively. Finally, it could be found that the volume loss was drastically reduced by raising the amount of zinc oxide, thus exceeding the composite minimum amount, which represents the total percentage of zinc oxide (10 percent).
