Assoc. Prof. Pavel Souček and Dr. Peter Klein traveled to Tokyo Metropolitan University, Japan. They planned pilot experiments on the research of X2BC-based thin films. Assoc. Prof. Tetsuhide Shimizu invited them to Japan as their colleague. They worked in his Tokyo lab at the end of July 2023.
Japanese colleagues specialize in HiPIMS thin film deposition technology and its evaluation. More specifically, they are working on the development of hard and yet flexible protective coatings. Dr. Klein comments on their research, "Nowadays, the industry demands new types of materials that have good hardness but also toughness and flexibility. Companies are no longer interested in coatings just for machining that can withstand mechanical stress. The Nb2BC system could become one such material."
In the past, Tetsuhide Shimizu has worked with various European groups, e.g., Ulf Helmersson's group in Linköping, Sweden. From multiple scientific meetings, he is familiar with our scientists from Prof. Vašina's research group, Deposition of Thin Films and Nanostructures, at the Department of Physics and Technology and CEPLANT. Tetsuhide Shimizu focused on magnetron sputtering later in his scientific career as a materials engineer, and he and the scientists at the DPPT are now working together on the deposition of thin films based on the Nb2BC system and the diagnosis of the deposition process.
