Using titanium, boron carbide and iron-based alloy powders as reactive sources, an Fe-based cladding coating reinforced by in situ synthesised TiC-TiN particles was fabricated using the plasma cladding method. The effects of Ti and B 4 C content on the phase composition, microstructure, microhardness, wear resistance and corrosion resistance of the coating were studied. The cladding coatings were composed of α-Fe, Cr, Fe 3 C, TiC, TiN, Fe 23 B 6 and Fe 23 (C, B) 6 . The relative content of TiC, TiN, Fe 23 B 6 , and Fe 23 (C,B) 6 in the cladding layer increased with an increase in Ti and B 4 C contents. The hardness, wear resistance and corrosion resistance of the cladding coating increased with an increase in Ti and B 4 C content. The results indicated that the composite coatings exhibited excellent wear resistance and corrosion resistance.
