A new hardfacing process, reactive braze coating process (RBCC) was studied, and ( TiC + Cr3 C2 ) /Fe composite coatings were prepared by RBCC using carbon, Cr3 C2, iron, ferrochromium and titanium powder as the raw materials in vacuum braze furnace. The results show that TiC is in-situ synthesized in the coatings. The methods of introducing Cr3 C2 have great effects on the distribution of TiC. Adding Cr3 C2 directly to the raw materials for coatings, fine TiC particles aggregate into discoids parallel to the coating surface, whereas, in-situ synthesizing Cr3 C2 in coatings, the aggregations of TiC are lumpish. During braze coating, Cr3 C2 particles directly added dissolve and precipitate to become needle-shaped. The coatings have an even and smooth surface and are combined with their mild steel substrates by a metallurgical bonding.
