How to Choose the Right IN939 Powder

Att välja rätt IN939 powder depends on factors such as particle size distribution, powder morphology, atomization process, and application requirements.

1. Particle Size Distribution (PSD)

• Fine powders (15-45µm) → Best for Laserpulverbäddfusion (LPBF)
• Medium powders (45-105µm) → Suitable for EBM & Binder Jetting
• Coarse powders (50-150µm) → Used in Deposition med direkt energi (DED)

2. Powder Morphology

• Sfäriskt pulver → Best for 3D-utskrifter due to superior flowability
• Irregular Powder → Suitable for Binder Jetting & Sintering

3. Atomization Process

• Gas-Atomized Powder → High purity, excellent flowability, best for 3D-utskrifter
• Water-Atomized Powder → More affordable, irregular shape, best for sintering & MIM

Jämförelse

1. Atomisering av gas

How It Works:

• Molten IN939 is atomized using high-pressure inert gas (argon or nitrogen), rapidly cooling the droplets into fine, spherical particles.

Fördelar:
✔ High sfäriskhetvilket gör den idealisk för 3D-utskrifter
✔ Low oxygen content, reducing oxidation risks
✔ Konsekvent fördelning av partikelstorlek, improving packing density

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

2. Atomisering av vatten

How It Works:

• High-pressure water jets break molten IN939 into fine particles, resulting in irregular-shaped powders.

Fördelar:
✔ Lägre kostnad than gas-atomized powders
✔ Higher surface areavilket gör den lämplig för sintering and MIM

Nackdelar:
✖ Poor flowability for additive manufacturing
✖ Higher oxygen content, which may require additional processing

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

3. Plasma Rotating Electrode Process (PREP)

How It Works:

• A rotating IN939 electrode is melted in a plasma environment, forming highly spherical, ultra-pure powders.

Fördelar:
✔ Perfect spherical shape, excellent for high-end AM
✔ Ultrahög renhet, suitable for aerospace and medical applications
✔ Superior flowability

Nackdelar:
✖ Dyrt
✖ Limited production volume

Best for: Aerospace, industrial gas turbines, and precision engineering
