Using the compounding of graphite, Fe-Ti, Fe-V and rutile, the carbides TiC and VC with high micro hardness,were formed by arc metallurgic reaction. The effect of the contents of graphite, Fe-Ti, and Fe-V in the coat on the crack resistance and hardness of hardfacing metal were also discussed. The microstructure, fracture feature of hardfacing metal and distribution of TiC,VC in the matrix were analyzed by means of X ray diffraction, SEM and EMPA. The results show that the microstructure of hardfacing metal was lath martensite and retained austenite with carbides which are dispersively distributed in the matrix. The hardfacing metal has high plasticity and ductility. Its hardness was more than HRC55, however, the crack of hardfacing metal did not occur even under conditions of non preheating and non postheating. The hardfacing metal has a high wear resistance, and its relative wearability is better than that of D667.
