Powder metallurgy
We are active in the field of powder metallurgy in the area of obtaining advanced engineering and functional materials by sintering powders of metals, ceramics, metal matrix composites (MMCs), ceramic matrix composites (CMCs), nanolaminar multilayer carbides (MAX phases), and poorly sinterable materials using the FAST/SPS method. We conduct high-energy ball milling and mechanical synthesis of powders in a protective atmosphere with temperature and pressure control. Qualitative and quantitative studies of powders, bulk materials and thin coatings are carried out by X-ray diffraction XRD and GIXRD, thanks to access to the full ICDD PDF-4+ database.
Our products are used in the space industry, as well as in bioengineering or batteries. They are used to protect surfaces from corrosion or temperature.
Manufacture of materials by spark-plasma sintering technology
- The spark-plasma sintering method allows sintering under high temperature and high pressure conditions. This offers the possibility of non-stoichiometric synthesis and obtaining solid sinters.
- Rapid manufacturing of innovative materials difficult or impossible to obtain with traditional technologies
- Possibility of sintering materials with melting points above 3000°C in up to tens of minutes (from powder to finished sinter).
We have the largest SPS device in Poland

High Energy Ball Milling (HEBM)
Powder preparation is a very important step in sintering or spraying processes. In our typical studies, we use high-energy ball milling and mechanical synthesis of powders. A specialist can control the temperature and pressure during the milling process. Phase transformations can be controlled by X-ray diffractometry.
