Purpose -The main goal of the present study is to investigate the friction and wear behaviors of aluminum matrix composites with an A360 matrix reinforced with SiC, B 4 C and SiC/B 4 C particles. Design/methodology/approach -Un-reinforced aluminum casting alloy, Al/SiC, Al/B 4 C and Al/SiC/B 4 C aluminum composites were prepared for the present study. Friction and wear tests of aluminum and its composites versus AISI316L stainless steel were carried out for dry sliding condition using by a pin-on-disc arrangement. Tests were realized at the sliding speed of 0.5, 1.0 and 1.5 ms 2 1 and under the loads of 10, 20 and 30 N. The microstructures of the present composites were examined by scanning electron microscopy and energy dispersive spectroscopy analysis. Findings -The coefficient of friction of the composites is approximately 25-30 percent lower than that of the un-reinforced aluminum. The specific wear rate of the aluminum and its composites decreases with the increase in load and increases with the increment of sliding speed. Un-reinforced aluminum has specific wear rate value of 1.73 £ 10 2 13 which is the highest specific wear rate, while Al þ 17%SiC has specific wear rate value of 2.25 £ 10 2 13 m 2 N 2 1 which is the lowest specific wear rate among the tested materials. The average specific wear rates for Al þ 17%B 4 C, Al þ 17%SiC/B 4 C and Al þ 17%SiC composites are obtained about 49, 79 and 160 percent lower than aluminum wear rate under the same test conditions, respectively. Originality/value -In the present study, composites were prepared by pressured infiltration technique. The employed composites are important in industry due to their higher wear resistance, light in weight and less thermal distortion comparing to conventional composites. Also, wear behavior of Al/B 4 C, Al/SiC/B 4 C and Al/SiC composites produced by pressured infiltration technique were not studied very much earlier, therefore more explanation about these composites were proposed.
