The invention discloses nickel-based alloy powder for laser cladding, ceramic particle reinforced composite powder and application. Alloy elements of the nickel-based alloy powder for laser cladding comprise Cu, Cr, Mo, Fe, C, Si, B and Ni. The mass of Cu, the mass of Si and the mass of B account for 10%-15%, 0.02%-1% and 0.01%-0.5% of the total mass of the nickel-based alloy powder correspondingly. The nickel-based alloy powder can be independently used for laser cladding and can also be mixed with high-proportion (50%-75%) hard ceramic powder to form the ceramic particle reinforced composite powder, and on the premise that it is guaranteed that a laser cladding layer does not crack, the hardness and abrasion resistance of the laser cladding layer are improved.
Description
technical field [0001] The invention belongs to the technical field of laser cladding materials, and in particular relates to a nickel-based alloy powder for laser cladding, ceramic particle-reinforced composite powder and their application. Background technique [0002] As a new surface modification technology, laser cladding adds cladding materials to the surface of the substrate, and uses a high-energy laser beam to melt it and a thin layer of the substrate surface at the same time, and quickly solidifies to form a substrate material. into a metallurgically bonded cladding layer. The main application directions of laser cladding technology are (1) laser remanufacturing: through cladding wear-resistant alloy coatings on key parts of parts, the strengthening and remanufacturing of parts can be realized; (2) high-performance cladding on the surface of ordinary materials The material thus replaces the overall use of high-performance materials, which has the effect of reducin...
