| Abstract: | Microstructure change of compressed composite powder block in mould cavity with metal poured and solidified on was examined using SEM and XRD. It was confirmed that the V 8C 7 particles reinforced iron matrix surface composites can be in situ produced on the casting surface using cast-sintering technology. The mechanism of vanadium quick carbonizing and composite powder fast sintering and compacting of the compressed block during casting was investigated.Wear resistance of V 8C 7 particle reinforced iron surface matrix composite was examined using MM-200 wear-test machine. |
