Study of Nickel-Based Composite Coatings on H13 Steel Surface by Laser

Abstract:

NiCrBSi+Ti+C and NiCrBSi+TiC composite coatings were fabricated on H13 steel substrate by laser claddings to improve its wear resistance. The macroscopic qualities of the coatings were analyzed and the process parameters and the clad materials were optimized. The microstructure of the coatings was characterized by SEM. The microhardness of the coatings was examined using HXD-1000 microhardness tester. The wear properties were examined using M-200 wear test machine. The results show that the clad materials and the process parameters are the important factors to influence the quality of laser cladding. Ni+Ti+C organization is smaller, particle strengthening and grain refinement is more significant. The hardness of the clad coating of NiCrBSi+Ti+C coatings reaches HV900, which is improved by almost three times compared with the substrate H13 steel.
