Summary: | The invention discloses high-temperature-resistant high-wear-resistant nickel-based titanium carbide powder and a preparation method thereof, and belongs to the technical field of surface engineering.The powder comprises 50-75% of TiC and 25-50% of NiCrAlSiX, wherein in NiCrAlSiX, Cr accounts for 20-23%, Al accounts for 7-10%, Si accounts for 1-2.5%, X is W+V, the total amount of X is greater than or equal to 3% and less than or equal to 8%, and the balance Ni. By adding Ni, the stability of Cr in an iron matrix is kept, the precipitation of Cr element in a spraying process is avoided, and the corrosion resistance of a material is improved; by adding a proper amount of Al, the dissolution of TiC can be inhibited, the hardness and toughness of a coating are kept, and meanwhile, the corrosion resistance of a composite material can be improved; by adding a small amount of boron, a spraying process window can be widened; and by adding 5-20% of Mo, the corrosion resistance and wear resistance of the coating are im |
