    The laser cladding technique is adopted for the fabrication of 2205 dual-phase stainless steel/TiC composite coating on the 16Mn steel surface. The effect of TiC content on the microstructure, microhardness and frictional wear properties of cladding layer is investigated and the relationship between the melting and precipitation behaviors of TiC in the cladding layer and the properties of cladding layer is also discussed. The results show that the dilution rate of cladding layer increases gradually with the increase of TiC content. Moreover, the TiC particles melt and precipitate during the laser cladding process. The microhardness of cladding layer increases gradually as the TiC content increases, and the highest microhardness of cladding layer is up to 612 HV when the TiC mass fraction is 15%. Simultaneously, the wear weight loss of cladding layer is the lowest.
