Important results from the project
** Denna text är maskinöversatt ** Through a successful collaboration with RISE and Umeå University, technologies available at large science facilities have been identified as suitable for analysis of the processes that degrade an optically selective coating at high temperatures. More specifically, detailed analysis of diffusion and chemical change of chromium in the coating with X-ray-based techniques at SOLEIL in France is planned.
Expected long term effects
** Denna text är maskinöversatt ** The planned experiments with the identified techniques are expected to be able to characterize the degrading processes in detail. With increased understanding, the expectation is that the result will lead to adjustments of the coating which counteract the degrading processes effectively. If this is the case, the coating is ready to be scaled up and commercialized, which would bring major strategic as well as economic benefits for Absolicon.
Approach and implementation
** Denna text är maskinöversatt ** The project has been hampered by the current pandemic. But effective collaboration between the project parties and external experts has nevertheless enabled a successful project where the goals have been met and a clear path forward has been set out. In addition to fulfilling the goal of identifying suitable techniques, additional analysis which will benefit the parties has also been carried out.
