A nickel alloy powder, a method of making and using the same

Abstract

This invention relates to the field of additive manufacturing technology, specifically proposing a nickel alloy powder, its preparation method, and its applications. The raw materials include Ni 50-85%, Cr 10-20%, Co 5-12%, Mo 3-8%, Al 0.5-2.5%, Ti 0.3-1.5%, C ≤0.08%, nano-carbide particles 0.06-0.08%, Y₂O₃@Ni core-shell structure particles 0.3-0.5%, rare earth elements 0.05-0.5%, and the balance being unavoidable impurities; the nano-carbide particles are at least one selected from TiC, WC, and SiC; the rare earth elements are at least one selected from Ce and La. Compared to traditional atomization methods, this invention, through nanoparticle modification and pulsed processing, systematically solves the problem of closed-pore defects in nickel-based superalloy powders.
