The aluminium metal matrix composite reinforced with ceramic material of Silicon carbide (SiC) has good mechanical properties. However, aluminium based ceramic composites require improvements in their lubrication and tribological properties. In this study an attempt is made in the development of a new material through powder metallurgy technique by the addition of Graphite, which acts as a solid lubricant. This work investigated the influence of graphite on the wear behaviour of Al 7075/SiC /X wt.% graphite(X=0, 5 and 10) hybrid composite. The investigation reveals the effectiveness of incorporation of graphite in the composite for gaining wear reduction. The Al 7075 (aluminium alloy 7075) reinforced with SiC –graphite were investigated. The composites were fabricated using powder metallurgy route. The microstructures, material combination, wear and friction properties were analysed by scanning electron microscopy, XRD, and pin-on-disc wear tester. The newly developed aluminium composite has significant improvements in tribological properties with a combination of 5% Silicon carbide (SiC) and 5% Graphite. The test reveals that sliding distance of 1000 m and sliding speed of 1.5 m/s with applied load of 5 N result in minimum wear loss of 0.01062g and coefficient of friction as 0.1278.

Diffusion Enhancement

In this paper, several copper matrixes reinforced with 1 wt. % silicon carbide (SiC) were fabricated using powder metallurgy (PM). The effect of sintering time (30 min, 60 min, 90 min, and 180 min) on composite density and porosity, and grain size were investigated. The results showed that longer sintering time gives higher sintered density, and smaller porosity content. This is due to the diffusion enhancement, which leads to reduce pore size, and close porosities. Also, for a given compaction pressure, the grains tend to be coarser for longer sintering time, due to the materials tendency to reduce grain boundary surface energy. In addition, samples compacted at high pressure have finer grain than corresponding grains compacted at low pressure but sintered for the same time.
