Production & characterization of high quality metal powders


Metal powders

Powder metallurgy allows new and creative ways to form metal: complex shapes, new properties, innovative coatings and reduced costs. This potential can be further unlocked with engineered metal powders produced using optimized atomization processes.

Our powder platform, covering the entire range of metal compositions, consists of multiple pilot-scale processes with complementary technologies, allowing us to accompany our industrial partners in their product and process development projects. Our characterization facility provides insight into powder quality and behaviour to go beyond simply respecting technical specifications.

Gas atomization provides multiple advantages for metal powders including metal quality and sphericity for use in various processes.

The technology at IRT M2P also allows maximum flexibility in terms of available metals, particle sizes and batch quantities between 5 and 200 kg (depending on alloy).

Electrode Induction melting Gas Atomization (EIGA)
Crucible free induction melting: no refractory pollution resulting in ultra-high purity powders
Free-fall argon atomization
Feedstock = pre-existing ingots or electrodes with the possibility to produce these using other furnaces at IRT M2P
Little or no oxygen/nitrogen pick-up between feedstock and powder

Vacuum Induction melting Gas Atomization (VIGA)
Close-coupled atomization for reduced particle sizes
Refractory crucible allows the production of a wide range of alloys and good chemical homogeneity prior to atomization
Possibility to use argon or argon/O2 atomization gas in order to optimize passivation

Sieving under protective atmosphere
Customized batches for various powder metallurgy technologies (LBM, EBM, HIP, SPS, thermal spray etc.)

Chemical analysis, physical characterization & powder behaviour

The EIGA and VIGA contain multiple sensors and a system to store/ analyze all data with the possibility to validate existing models
Studies on liquid metal/gas interaction
Thermal and high-speed cameras
