Wear and corrosion measurements (pin-on-disc, galvanostatic) writes about us

An article about our project, which has just been completed, was published on the most read website about events in Pilsen. Read here.

Publications (articles from conferences and journals) published within the project can be downloaded here.

We want to keep up with recent trends and news, therefore we participate on various events.

You can meet us 25th September in Augsburg at the Clusterseminar about 3DPrint.
