<p>In this paper, the design, microstructure characterization and friction properties of in situ synthesized TiC-reinforced Fe-based composite coatings by powder-assisted wire arc surfacing were studied. TiC-reinforced Fe-based surfacing layer was successfully prepared by surfacing on Mn13 substrate with 1Cr17 solid core stainless steel wire and self-developed Fe-based alloy powder. The results show that TiC particles are successfully synthesized in situ and uniformly distributed in the surfacing layer. The microstructure analysis shows that TiC particles, as the core of non-spontaneous nucleation, refine the grain structure and play a stirring role in the molten pool, which destroys the dendrite growth and optimizes the microstructure of the coating. The presence of TiC significantly improved the microhardness of the coating, and the average hardness reached 650.0 ± 25&#xa0;HV, which was significantly higher than that of the substrate. In the dynamic load abrasive wear test, the wear resistance of the surfacing sample is better than that of the Mn13 steel substrate, and the wear amount is significantly reduced under different impact energies. In addition, the friction coefficient of the surfacing layer is lower than 0.4 and relatively stable, and the friction performance is significantly improved. This study provides a theoretical basis and experimental support for the preparation of high-performance coatings by solid wire combined with powder surfacing.</p>
