Current metal-based additive manufacturing (AM) technologies require high quality powders that must possess some critical properties, in order for the processes to behave in a reproducible way. Among other properties, they must be spherical, satellite-free, with a high-packing density, of a specific particle size distribution (PSD), highly flowable and free of porosity.
The challenge is that commercially available materials rarely meet all these requirements. In order to address this challenge, Tekna has developed two core technologies: RF plasma spheroidization (RF-PS) and RF plasma atomization (RF-PA). Depending on the nature of the feedstock (recycled powders, milled turning chips, wires, etc.), one can develop new materials, which were not available by conventional production techniques.
By offering new, innovative and cost-effective approaches to powder metallurgy, these plasma processes are currently facilitating the development of new materials across the world and accelerating their introduction to market.
