How to Choose the Right IN738LC Powder

Välja rätt IN738LC powder requires considering factors such as particle size distribution, powder morphology, atomization process, and specific 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

How It Works:

• Molten IN738LC is atomized using high-pressure argon or nitrogen gas, rapidly cooling the droplets into fine, spherical particles.

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

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 fragment molten IN738LC, producing irregular-shaped powder particles.

Fördelar:
✔ Lägre kostnad compared to gas-atomized powder
✔ Higher surface area, improving sintering efficiency

Nackdelar:
✖ Poor flowability, making it unsuitable for many AM processes
✖ Higher oxygen content, requiring additional post-processing

Best for: MIM, sintering, and thermal spray coatings

3. Plasma Rotating Electrode Process (PREP)

How It Works:

• A rotating IN738LC electrode is melted in a plasma environment, forming highly spherical, ultra-pure powders.

Fördelar:
✔ Nearly perfect spherical shape, ensuring outstanding flowability
✔ Ultrahög renhetvilket gör den idealisk för aerospace and medical applications
✔ Minimal satellite particles, leading to superior print quality

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

Best for: Aerospace, medical implants, industrial gas turbines
