• Coarse powders (50-150µm) → Used in DED (Direct Energy Deposition)

2. Powder Morphology

• Spherical Powder → Best for 3D printing and powder bed fusion technologies
• Irregular Powder → Suitable for Binder Jetting & Sintering

3. Atomization Process

• Gas-Atomized Powder → High purity, excellent flowability, best for 3D printing
• Plasma-Atomized Powder → Ultra-high purity, best for specialized aerospace applications

Advantages:
✔ Highly spherical particles, improving powder flowability and printability
✔ Low oxygen content, preventing oxidation defects
✔ Excellent particle size uniformity, ensuring consistent layer deposition in AM

Best for: Laser Powder Bed Fusion (LPBF), Electron Beam Melting (EBM), and Direct Energy Deposition (DED)

2. Plasma Atomization (PA)

Process:

• CMSX-4 wire is fed into a high-energy plasma torch, melting it into fine droplets that form highly spherical powder particles.

Advantages:
✔ Perfect spherical shape, ensuring superior flowability
✔ Ultra-high purity, making it ideal for jet engines & aerospace
✔ Minimal satellite particles, leading to superior print quality

Disadvantages:
✖ Higher production costs
✖ Limited scalability for large-scale production

Best for: High-performance aerospace and gas turbine components

3. Vacuum Induction Melting + Gas Atomization (VIGA)

Process:

• CMSX-4 alloy is melted in a vacuum induction furnace and then atomized under inert gas conditions, producing high-purity powders.

Advantages:
✔ Ultra-high purity, ideal for critical aerospace applications
✔ Excellent control over alloy composition
✔ Superior mechanical performance post-processing

Disadvantages:
✖ Very high cost
✖ Longer processing time

Best for: High-performance turbine components and precision aerospace applications
