Experimental Study of Wear Rate Coefficient of Aluminium Hybrid Composites Manufactured By Stir Casting Technique
Journal Title: International Journal of Innovative Research in Advanced Engineering - Year 2016, Vol 0, Issue 0
Abstract
In current decade, demand in material characteristics like light weight, superior strength to weight ratio, improved surface properties and enhanced wear resistance for complex engineering applications like automobile, aerospace and nuclear are researcher’s interest. However, performance of hybrid composites depends on right combination of reinforcements. Silicon carbide, silicon nitride, boron nitride and titanium carbide are few reinforcements available at present. In this work, Al356 is reinforced with SiC and B4C to enhance the mechanical properties, surface hardness and wear resistance. This hybrid composite is prepared by stir casting technique and the morphology of composite is studied using optical microscope to investigate the dispersion of reinforcements. In the present study, the wear and friction characteristics of hybrid composites are investigated using pin on disc dry wear tests by varying the load and speed and the results are tabulated for load vs mass loss, load vs wear rate and load vs wear coefficient. The results report that wear rate of hybrid composites are lower than that of binary composites. Mechanical properties, surface hardness and wear characteristics of aluminium hybrid composites are compared with that of aluminium binary composites available at present.
