【 摘 要 】

The work is done to research the dry sliding wear behaviour of B4C strengthened Al7010 alloy metal composites. Here Al7010 was used as matrix material and B4C as particulate to get MMC by vortex technique. For MMC the reinforcement was varied from 3% to 12 wt. % in venture of 3 wt %. The micro structural characterization was done by using scanning electron microscope and energy dispersive spectrographs to reveal the uniform distribution of particles and also to confirm the B4C particulates. The wear resistance of metal matrix composites was reported by experimenting wear test using a pin on disc apparatus. The experiments were carried out at a constant sliding speed of 300rpm and sliding distance of 2000m over a varying load of 2, 3 and 4Kg. Similarly experiments were conducted at a constant load of 3Kg and sliding distance of 2000m over a varying sliding speed of 200, 300 and 400rpm. The results showed that the wear loss in microns found to increase with the load and sliding speed. To concentrate the dominant sliding wear component for different test conditions, the worn surfaces were analyzed using SEM.
