TiC and TiB 2 reinforced iron based metal matrix composite (MMC) coating was synthesized on mild carbon steel by laser cladding employing B 4 C , ferrotitanium, and FeCrSiB mixed powders. The microstructure and chemical composition were analyzed by means of SEM, EPMA, and XRD. Results show that the coating mainly consists of α– Fe(Ni) , TiB 2, TiC , B 6 Fe 23, Cr 2 B , and M 23 C 6. TiB 2, and TiC reinforcements are formed in situ through the reaction between B 4 C and ferrotitanium. Hardness and wear measurement results show that the hardness and wear resistance of the composites are much higher than that of the as-received sample.
