The influence of matrix microstructure and particle reinforcement the two-body abrasive wear of an Al-Si alloy

摘要

New materials such as metal matrix composites are now preferred for superior working efficiency. Efforts are being made to develop lightweight, wear-resistant materials by dispersing hard ceramic Prides such as SiC [1,2], A12O3 [3,4], [5], SiC>2 [6] etc. in aluminium alloy for various engineering applications [7-9]. the various hard particles used for preparing Particle reinforced MMCs, zircon (ZrSiC>4) is found to be a promising reinforcement due to its low cost, lo thermal expansion coefficient, high hardness and go0d machining behaviour, which may be suitable for various engineering applications such as brake 'otors, inlet of slurry pumps, cyclone (mineral Processing equipment) parts etc.
