Abstract

Abstract

Ti-Fe-C composite powders for Reactive Flame Spray (RFS) were prepared by precursor carbonizationcomposition process using ferrotitanium and asphalt as raw materials. TiC/ Fe composite coatings were synthesizedand deposited by RFS. The influence of C/ Ti atomic ratio on the component, microst ructure and hardness of thecomposite coatings was investigated. The result s show that C/ Ti atomic ratio has st rong influence on the component, microst ructure and hardness of TiC/ Fe composite coating. The TiC aggregate size and porosity of TiC/ Fecomposite coating increase with the increase of the C/ Ti atomic ratio.
