Abstract
In this paper, the effect of in-situ (Ti&W)C multiphase particles on the microstructure and the three-body abrasive wear behavior of high chromium cast iron was investigated. The results reveal that the different W/Ti ratios in the preforms can lead to significant differences in the microstructure and properties of the composites. The best microstructure and wear resistance of the composite (M3) is achieved when the W/Ti ratio is 4/6. Under the same wear conditions, the wear resistance of the M3 composite is more than twice as high as that of the matrix material. Furthermore, the presence of (Ti&W)C multiphase particles in the microstructure improves the hardness of high chromium cast iron, promoting its transition from cutting, fatigue, and the M7C3 fracture-exfoliation wear mechanism in the abrasive wear to micro-cutting and fatigue wear.
