The objective of this study is to develop chromium-reinforced metal–metal composites utilizing an AA5083 aluminum alloy matrix through powder metallurgy while also examining their properties. Samples were produced by incorporating varying quantities of chromium (5%, 10%, and 15% by weight) into the AA5083 matrix. In order to ensure a uniform distribution of chromium particles, the powders were blended in a ball mill and subsequently hot-pressed at 500 °C under 500 MPa for a period of two hours in an argon atmosphere. The resulting samples were subjected to analysis in order to determine the effect of chromium content on the composites, with particular attention being paid to their microstructure, hardness, density, tensile properties, tribological performance and corrosion resistance. The findings demonstrated that an elevated chromium concentration markedly augmented the hardness of the composite, exhibiting a 50% enhancement in the 15 wt.% Cr composite. A 30% reduction in wear loss was observed for the same sample. The A10 sample (10 wt.% Cr) exhibited the greatest corrosion resistance, although this declined in the A15 sample due to increased porosity. Tensile strength increased by up to 10 wt.% Cr before decreasing at 15 wt.% Cr, which was also attributed to porosity. These findings demonstrate that chromium reinforcement enhances the mechanical and tribological performance of AA5083 composites, rendering them suitable for applications requiring high hardness and wear resistance.
