Description: Iron-nickel-chromium-molybdenum-based powder material and preparation method for laser cladding, belonging to the technical field of surface engineering. Percentage by weight of each component of the powder: titanium powder: 10-18wt%; Graphite Toner: 2-4.5wt%; niobium carbide powder: 6-15wt%; iron - nickel - chromium - molybdenum alloy powder... : margin; wherein iron - nickel - chromium - molybdenum alloy powder composition is as follows: Nickel: 20-26wt%, Cr: 23-26wt%, Mo: 6-15wt%, Fe: balance.... Advantages: the use of high energy density of the laser beam to melt the mixed powder, the steel substrate surface to form iron - nickel - chromium - molybdenum alloy as the continuous phase, in order to enhance the wear and corrosion carbide ceramic cladding phase cladding to achieve metallurgical bonding with the substrate, the dilution rate. The method of the present invention has a lower production cost, cladding corrosion wear-resistant long life, the process is relatively simple, etc., can significantly extend the life of wear and corrosion agitator slurry circulating pump and water circulation pumps and other components.
