Fe-WC surface composites produced by reactive cast-infiltration

The reactive cast-infiltration technique was used to produce an Fe-WC surface composite laer on an iron casting, in which the WC particulates were formed in situ from a reaction of W with C. The structure and phase construction of the surface composite were evaluated by using X-ray diffraction (XRD)...

Description
Summary:The reactive cast-infiltration technique was used to produce an Fe-WC surface composite laer on an iron casting, in which the WC particulates were formed in situ from a reaction of W with C. The structure and phase construction of the surface composite were evaluated by using X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray (EDS), etc. An Fe-WC surface composite layer witha volume fraction of WC particles up to30% and particle size in the range 10-30 μm was successfully produced. Abrasive resistance test results show that the Fe-WC surface cmposite layer possesses great abrasive resistance.
