STRUCTURE AND WEAR-RESISTANCE OF Fe-VC SURFACE COMPOSITE PRODUCED BY LIQUID REACTIONS

Using liquid surface reaction technique, Fe VC surface composites with thickness of 3～4 mm were produced on casting steel. The microstructure and phase of Fe VC surface composite were studied by light microscope, SEM and XRD. The distribution of alloy elements in this surface composite was analysed by Electron probe with wave spectrum. Under condition of dry sliding with heavy loads, Fe VC surface composite holds great wear resistance.
