Properties of SiC/Fe Composites Prepared by Coating Process and Powder Metallurgy Method

摘要：

　　SiC particulate-reinforced Fe composites were prepared by a powder metallurgy (PM) and conventional atmospheric sintering method.X-ray diffraction (XRD),scanning electron microscopy (SEM) techniques were used to characterize the obtained composites.The coating layer of Cu on SiC particles can suppress the reaction between SiC and Fe until 1250℃.The maximum microhardness of 283 Hv appears at near 1250℃.Substantial reaction occurs at above 1250℃,which leads to the deterioration in the microstructure and related properties.The inter-metallic compounds of FeSi or Fe2Si were detected which contributed to the enhancement of the interface between SiC and Fe.
