CoE-IoP – Cluster of Excellence "Internet of Production" - Subproject WS-B2.II “Discontinuous Production”

Short description:

Within the subproject WS-B2.II “Discontinuous Production”, different aspects of Industry 4.0 are investigated. Artificial intelligence methods are used to predict particle properties based on process parameters. The creation of a digital shadow of the TS and PVD coating processes will be implemented by a digital networking of the coating equipment in combination with process simulations. Furthermore, a digitized connection of the analysis equipment and automated transfer to a database will be implemented. The collected data will be used to predict coating properties and for specific control and parameter selection for the coating process. Poster CoE IoP Subproject WS-B2.II

Theleis – Thermally sprayed coatings with good thermal conductivity and electrical insulation

Short description:

In this research project, a thermally sprayed coating is developed which has good thermal conductivity and at the same time ensures the electrical insulation of electrical components. This is implemented in cooperation with the project partner obz innovation GmbH. Increasing the power densities, especially in fast charging in e-mobility, lead to rising operating temperatures of the power electronics. Therefore, an adequate heat dissipation for electrical components while maintaining the electrical insulation is necessary. By varying the material chemistry and the microstructure of the applied coatings, the thermal resistance of the insulation coating is to be reduced without limiting the insulating effect. The functionality of the developed Theleis coating can be verified with the aid of application-oriented tests.

HEA-Heiz – Development of Novel Metallic Additional Materials for Heating Elements by Thermal Spraying

Short description:

This research project focuses on the investigation of high entropy alloys (HEA) for the application as thermally sprayed heating elements. HEA is a new innovative material class, which gained significant research interest in the last 15 years. By alloying elements with significantly smaller or significantly larger atomic radii the crystal lattice of the reference alloy is distorted to adjust the material properties that way. The metallurgic material development is conducted on alloys, remolten in a vacuum oven, as well as on metallic foils, which are manufactured by melt spinning. The high cooling rates of the alloy during melt spinning are used to emulate the solidification process during thermal spray. Poster HEA-Heiz
