文摘Fe-Cr-C cermet was prepared by reaction sintering of ferrochromium and graphite.The exothermic reaction was determined by DTA.The effect of carbon content on the porosity,hardness and oxidation resistance was investigated.The result showed that the cermet with 6%-7%of carbon has high hardness and oxidation resistance.
