At the Dörrenberg StudienAWARD 2021 award ceremony, Mika León Altmann was delighted with an outstanding 2nd place. His Bachelor's thesis on the resistance to impact fatigue of tungsten-doped hydrogen-containing amorphous carbon layer systems (a-C:H(:W)), which he developed at Leibniz-IWT under the supervision of Dipl.-Ing. Henning Hasselbruch, received excellent marks and convinced the jury.

The award ceremony for the 13th Dörrenberg StudienAWARD took place on 25 August. The young talent award honours excellent final theses by students who deal with materials technology issues relating to steel, heat treatment, surface technology or process engineering.

Five entries made it to the final round, in which the jury members had a hard time making a decision, as all the papers and presentations were of a very high quality: "It is impressive how competently and confidently our budding professionals present themselves," praised jury member Prof. Zoch. In the end, second and third place were each awarded to two prize winners.

Mr Mika León Altmann had previously shown in his presentation how he investigated the fatigue resistance of different a-C:H(:W) multilayer coating systems under high-frequency punctual impact stress on the impact tribometer in his Bachelor's thesis. In this context, Mr Altmann used confocal laser scanning microscopy (CLSM) and scanning electron microscopy (SEM), among other techniques, for his analyses. These investigations served to evaluate the suitability of such coatings for use on forming tools for lubricant-free rotary swaging. This requires a high resistance to impact fatigue.

For his placement, he received prize money of 2500 euros and a small trophy made of stainless steel
