Nickel-based alloy powder for additive manufacturing
The granted patent US12006558B2 outlines a nickel-based alloy powder specifically designed for additive manufacturing applications. The claims detail the composition of the alloy powder, which includes various elements in specified weight percentages. Key components of the alloy include zirconium (Zr), titanium (Ti), aluminum (Al), tungsten (W), tantalum (Ta), molybdenum (Mo), niobium (Nb), and carbon (C), with precise ranges provided for each element. For instance, the alloy may contain 0.07 to 0.15% Zr, 3.9 to 4.3% Ti, and 0.09 to 0.14% C, among others. Additionally, the patent claims the production of this alloy powder through a method involving the atomization of a molten metal stream, which can utilize techniques such as liquid, gas, or centrifugal atomization.
Furthermore, the patent describes a method for creating three-dimensional components using the nickel-based alloy powder. This process involves layering the powder on a build platform, selectively fusing regions to form component layers, and repeating the layering and fusing steps as necessary to achieve the desired three-dimensional structure. The patent also encompasses the potential use of the alloy powder in various additive manufacturing processes, highlighting its versatility and applicability in producing nickel-based alloy components. Overall, the claims provide a comprehensive framework for the composition, production, and application of the nickel-based alloy powder in advanced manufacturing technologies.
