Two materials systems,Fe-Ti-C-Al and Al-Fe2O3,were selected in this paper to prepare steel casting with ceramic reinforced surface layer by a casting process combined with self-propagation high-temperature synthesis (SHS).During the process,high temperature steel molten was poured into a sand mould inside which was SHS preform,thus the SHS preform was ignited by the high temperature steel molten.As a result,a SHS reaction was happened and ceramic reinforcements were synthesized inside mould.After the penetration of steel molten and the scatter of ceramic reinforcement,a steel casting with an in-situ ceramic reinforced surface layer was obtained.
