How to Choose the Right NiAl20 Powder

Choosing the right NiAl20 powder depends on factors such as particle size distribution, atomization process, and specific application requirements.

1. Particle Size Distribution (PSD)

• 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
• Water-Atomized Powder → Cost-effective, irregular shape, best for thermal spray coatings & MIM

Production Methods

The method used to produce NiAl20 powder significantly affects its particle shape, purity, flowability, and overall performance. Choosing the right production method ensures optimal results for additive manufacturing (AM), thermal spray coatings, and sintering applications.

Comparison of Production Methods

1. Gas Atomization (GA)

Process:

• Molten NiAl20 is atomized using high-pressure inert gas (argon or nitrogen), rapidly cooling the droplets into fine, spherical particles.

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

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

2. Water Atomization (WA)

Process:

• Molten NiAl20 is broken into fine particles using high-pressure water jets, forming irregular-shaped powders.

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 post-processing

Best for: Metal Injection Molding (MIM), sintering, and thermal spray coatings

3. Plasma Rotating Electrode Process (PREP)

Process:

• A rotating NiAl20 electrode is melted in a plasma environment, forming fine, highly spherical powders.

Advantages:
✔ Perfect spherical shape, ensuring superior flowability
✔ Ultra-high purity, making it ideal for high-performance AM applications
✔ Minimal satellite particles, leading to superior print quality

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

Best for: Aerospace, high-end 3D printing, and defense applications
