The role of additively manufactured niobium alloy C103 substrate’s surface finish and corner geometry on the silicide diffusion coating’s performance
- Nb-based C103 is an increasingly relevant material for aerospace applications due to recent advances in additive manufacturing (AM). AM enabled complex component geometries, along with the associated surface roughness, are a challenge to the survival of environmental barrier coatings (EBCs), like R512E. EBCs are necessary to provide protection for the oxidation susceptible C103 substrates in elevated temperature, oxidizing environments.
Nb-alloys like C-103 (89 wt% Nb, 10 wt% Hf, 1 wt% Ti) or Nb-1Zr (~99 wt% Nb, 1 wt% Zr) are generally easier to fabricate and more workable than Mo-alloys although they have relatively lower strength than the latter.
Powder Metallurgy: C103 can be processed using powder metallurgy techniques, where it is pressed and sintered to create high-strength components.
Welding and Machining: The alloy is weldable and machinable, allowing for its use in complex assemblies and components.
Powder Preparation: The C103 powder is first prepared and characterized for its particle size, distribution, and purity to ensure it meets specific application requirements.
Powder Metallurgy: The powder is then compacted into a desired shape using a die or mold, followed by sintering at high temperatures. This process bonds the particles together, creating a dense and strong component.
3D Printing (Additive Manufacturing): For complex geometries, the C103 powder can be used in 3D printing technologies such as Selective Laser Melting (SLM) or Electron Beam Melting (EBM). The powder is layer-by-layer melted and solidified to form precise, intricate parts.
Post-Processing: After forming, the components may undergo additional processes like machining, welding, or surface treatment to achieve the final specifications and improve properties such as oxidation resistance.
Quality Inspection: The finished components are subjected to rigorous testing and inspection to ensure they meet the required standards for mechanical properties, dimensional accuracy, and surface finish, especially for critical aerospace or defense applications.
