摘要：

In this study, are presented and discussed effects of silicon on the abrasive wear behaviour at elevated temperatures of cobalt-based alloys such as Co-28Cr-4W-1.1C-3.2Si, Co-28Cr-4W-1.1C-4.1Si, Co-28Cr-4W-1.1C-5.2Si, respectively. Wear resistance of the materials were measured by a two body pin-on-disk wear tester with SiC and Al2O3 abrasives. The hardness of stellite 6 alloy increased with silicon addition. Wear resistance of stellite 6 with silicon addition has increased at low temperature but, decreased at high temperature. Microstructure of samples has been investigated by optical and SEM techniques.
