Overzicht van Powder Post-Atomization Treatment
Post-atomization treatment of powders is a critical step to modify and enhance the properties of metal powders after they have been atomized. This can involve several processes such as heat treatment, mechanical milling, sieving, and surface treatment. The aim is to improve the powder’s flowability, reduce particle size distribution, increase purity, and enhance other specific properties needed for various applications.
Key Processes in Post-Atomization Treatment
- Hittebehandeling: Used to relieve internal stresses, modify phase structures, and improve mechanical properties.
- Mechanisch frezen: Reduces particle size and refines the microstructure.
- Zeven: Ensures uniform particle size distribution.
- Oppervlaktebehandeling: Enhances the surface properties of the powder particles.
