Fabrication of Fe/TiC Surface Composite on Carbon Steel Using SMAW Process

In this research, SMAW process and mixture of graphite and ferrotitanium compounds were employed to in-situ fabricating of Fe/TiC composite on the surface of AISI 1045 steel. Thermodynamics of possible reaction and effects of chemical composition of primary reactant were studied. Results showed that maximum size and volume ratio of TiC reinforced particles was achieved in sample with graphite to ferrotitanium ratio of 18 to 82 that shows maximum hardness. Obtained composite`s hardness was increased 220 per cent in relates to un-reinforced sub-layer (220 to 712 Vickers).
