Experimental Analysis of Wear Behaviour of Reinforced Aluminium Metal Matrix Composites

The emerging world demands light, inexpensive and quickly processed materials. The Al/SiC/B4C metal matrix composites have light weight, wear resistance and high elastic modulus. The Al/SiC/B4C metal matrix composite has applications in many industries such as automobile, aerospace, marine etc. The main objective of the project is to investigate the wear behavior of Al/SiC/B4C metal matrix composites. In the present investigation, fabrication of Al6063-SiC MMC’s containing 0% to 15% weight of SiC/B4C of average particle size of 25 μm was prepared using stir casting method. The composites were also tested to investigate tensile strength, hardness, impact test, in addition to wear behavior as per ASTM standards. The results show the alloy reinforced with SiC/B4C particles exhibit superior hardness, tensile strength, impact, and wear resistance with hardness, ultimate tensile strength and wear resistance increased with increase in SiC/B4C content. The effect of different weight percentages of SiC/B4C in the metal matrix composites on hardness, impact test, microstructure, was studied.
