• Fine powders (15-45µm) → Best for LPBF (Laser Powder Bed Fusion)
• Medium powders (45-105µm) → Suitable for EBM & Binder Jetting
• 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 and high-performance applications

Production Methods

The production method of Stellite 6 powder significantly influences its particle morphology, purity, and overall performance. The right method ensures that the powder meets strict industry standards for additive manufacturing (AM), thermal spraying, and wear-resistant applications.

Comparison of Production Methods

1. Gas Atomization (GA)

Process:

• Molten Stellite 6 alloy is atomized using high-pressure inert gas (argon or nitrogen), rapidly cooling the droplets into fine, spherical particles.

Advantages:
✔ Highly spherical particles, improving 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:

• Stellite 6 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 aerospace and biomedical applications
✔ Minimal satellite particles, leading to superior print quality

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

Best for: High-performance aerospace and medical implants

3. Vacuum Induction Melting + Gas Atomization (VIGA)

Process:

• Stellite 6 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

4. Water Atomization (WA)

Process:

• Molten Stellite 6 is atomized using high-pressure water jets, forming irregular powder particles.

Advantages:
✔ Lower production cost compared to gas-atomized powder
✔ Higher surface area, improving sintering behavior

Disadvantages:
✖ Poor flowability, making it unsuitable for powder bed fusion processes
✖ Higher oxygen content, requiring additional heat treatment

Best for: Powder metallurgy, MIM, and hardfacing coatings
