A new process, flame spray synthesis (FSS), has been developed for producing ceramic containing composite coatings. By combining self propagation high temperature synthesis (SHS) and flame spraying, the cermet based material was synthesized and deposited simultaneously. TiC Fe coatings were deposited from commercial ferrotitanium, iron and graphite powders by the flame spraying synthesis process. Microstructure analyses revealed that TiC was synthesized during spraying, and that submicron and round TiC particles were dispersed within an iron matrix. Flame spray synthesized coatings were composed of alternate soft and hard layers, whose hardness were 3.0～6.0 GPa and 11～13 GPa, respectively.
