By means of an inherent elevated-temperature of poured liquid steel, a Ti-G-30wt% Fe preform, which was pre-placed in a mould cavity, was directly ignited and a combustion synthesis reaction took place.As a result, a TiC-Fe cermet coating with a thickness of about 10 mm was simultaneously synthesized on the solidified steel matrix. The synthesized coating exhibits a feature of graded composite structure,in which both the amount and size of TiC particles decrease gradually with an increasing distance from the furface of the coating. Moreover,by a proper casting technique, the pores formed during the combustion synthesis of the preform could be centrally distributed in 2 - 3 mm in outer layer of the coating. When this outer porous layer was worn off, the rest coating with a thickness of about 8 mm possesses a dense structure and a high abrasive wear resistance.
