Studying Some Mechanical Properties and Wear Resistance of Aluminum - Glass Composites

Abstract

The research is aimed to prepare an aluminum matrix reinforced with window glass particles with weight percentages of (1%,2%,3%,5% and 7%) ,with particle sizes varies from 75-150μm. Composite materials are prepared by using mechanical stir- casting method. The formation of vortex in aluminum melt helps dispersion of glass particles in aluminum melt . Electroless copper coating on glass particles is carried out to improve wetability between glass particles and aluminium melt. Many inspections and tests have been done such as microstructure, hardness inspection, compression test and dry sliding wear test type Pin-on Disk with different loads and at a constant speed and sliding distanceIt was found that addition of glass particles coated with copper to pure aluminum increases hardness , compression strength and wear resistance .
