Abstract

In this study, the effect of Si addition up to 8% Si on the abrasive wear and mechanical properties of Al-Si/60 vol.% SiC composites produced by pressure infiltration technique has been investigated. Optimum properties in terms of improved strength and abrasion resistance without significant loss in toughness were obtained when the matrix alloy contained 1% Si. At Si contents higher than 1%, dramatic decrease of toughness was accompanied a reduction in strength and abrasion resistance. (C) 2004 Elsevier B.V. All rights reserved.
