摘要：

(Al-11. 8Si-4. 0mg alloy)-zircon particle composites containing zircon particle volume fractions of 0. 15 and 0. 35 have been prepared by liquid metallurgy techniques. The low stress abrasion resistance of these composites was tested using a rubber wheel abrasion test apparatus. Material removal mechanisms during low stress abrasion of the composites appear to be governed by microfracture of zircon particles, leading to subsequent pit formation. There is a direct correlation between material removal mechanisms during fixed-depth scratch testing and high stress pin-on-drum abrasion. In both cases there was catastrophic fragmentation of the zircon particles.
