• 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

• Sfäriskt pulver → Best for 3D-utskrifter och powder bed fusion technologies
• Irregular Powder → Suitable for Binder Jetting & Sintering

3. Atomization Process

• Gas-Atomized Powder → High purity, excellent flowability, best for 3D-utskrifter
• Water-Atomized Powder → Cost-effective, irregular shape, best for thermal spray coatings & MIM

Produktionsmetoder

Den produktionsmetod av NiCrAlY powder determines its particle morphology, purity, flowability, and overall performance. The right manufacturing technique is crucial to ensure the powder meets the demands of additive manufacturing (AM), thermal spray coatings, and high-temperature applications.

Comparison of Production Methods

1. Gas Atomization (GA)

How It Works:

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

Fördelar:
✔ Hög sfäriskhet, improving powder flowability and layer uniformity
✔ Low oxygen content, preventing oxidation-related defects
✔ Utmärkt flytbarhet, ensuring consistent deposition in 3D printing

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

2. Water Atomization (WA)

How It Works:

• High-pressure water jets break molten NiCrAlY, skapa irregular-shaped powder particles.

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

Nackdelar:
✖ 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)

How It Works:

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

Fördelar:
✔ Perfect spherical shape, ensuring superior flowability
✔ Ultrahög renhetvilket gör den idealisk för high-performance AM applications
✔ Minimal satellite particles, leading to superior print quality

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

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