| Abstract | ||
| This work is production of aluminum matrix composite by powder metallurgy method .The samples have done when aluminum powder was used as a matrix in purity of (9.99%) and silicon carbide(α-SiC) as reinforcement material, the particle sizes were used which (125μm) at weight percentage (7.5% - 10% - 15%) from silicon carbide for each particle size. The purpose is to improve the hardness and wear properties of matrix .It was found that the hardness is increased with increment of the amount of added particles, due to the hardness of silicon carbid particles. From the wear test, it is found that the wear resistance increase with increasing the weight percentage of SiC particles, but the wear rate increase when the applied load increase for all the particles size and additional percentage. Also, it is found that when the sliding velocity increases, the wear rate also increases, but the best results were found in samples reinforced with (SiC) particles | ||
