Objective To study the microstructure and properties of TiC-Fe45-based composite coating by argon tungsten-arc cladding. Methods Through addition of Tic particles into the Fe45 self-fluxing alloy powder, the composite coating of Fe-based alloy reinforced by TiC particles was prepared by argon tungsten-arc cladding process. The microstructure, microhardness distribution and wear resistance of the coating were analyzed. Results The composite coating was composed of the dendritic ( Fe, Ni) -based matrix, interdendritic ( Fe, Cr)₂₃( C, B) 6, Fe₃( C, B) eutectic structure and TiC reinforcement particles. The TiC particles were dispersedly embedded into the matrix, and part of the particles were congregated into virgate, cross and radial shapes. Conclusion The microhardness of the composite coating could reach 980 HV, which was more than four times that of the substrate and the wear resistance was increased by nearly 11 times.
