| Abstract: | (Ti,W)C particle reinforced high chromium cast iron composite was prepared by in-situ synthesis and casting method. XRD, EDS, SEM and other detection methods were used to study the reaction process and three-body wear resistance of the composite. The results show that there is a reaction-melting-precipitation mechanism and a reaction-solid solution mechanism in the reaction process of the reinforcing phase (Ti,W)C particles. The interface between the (Ti,W)C particles and the matrix is metallurgical bonding. The wear resistance of the composite is 1.4 times that of the high chromium cast iron, and the wear mechanism is abrasive wear-adhesive wear. |
