Abstract

Abstract: Ni60A and (2%, 4%, 6%)TiC+Ni60A composite coatings were prepared on the surface of TC4 titanium alloy by laser cladding process. The influence of different TiC mass fractions on the microstructure and properties of the clad layer were analyzed by metallographic microscope, microhardness tester, X-ray diffractometer, and friction-wear machine. The results show that the microstructure of the clad layer without TiC is dominated by dendrites, and the TiC addition leads to the appearance of petal phase. The XRD analysis shows that hard reinforcing phases AlCCr₂, Al_0.24B_0.01Ni_0.75 appear in the clad layer, which can significantly increase the hardness of the clad layer. The results of microhardness and friction and wear tests show that the average hardness of the clad layer with TiC is significantly higher than that of the matrix, and the friction coefficient is significantly reduced. With the increase of TiC content, the hardness of the clad layer increases first and then decreases, while the friction coefficient decreases first and then increases. The hardness of the clad layer with 4% TiC is the highest, which is 213.3% higher than that of the matrix, and the friction coefficient is the lowest, which is 0.309 774.
