| Annotation: | After introducing the high entropy stabilized alloys and ceramics, research focused on bulk multicomponent borides and carbides of the transition metals (TM) forming single-phase compounds. Since 2014, these activities expanded also in bulk two-phase fcc+hexagonal/bcc (e.g. TM boride +TM carbide) or even multi-phase ceramics with improved properties. However, analogous two-phase boride-carbide coatings have been produced up to now neither by conventional DC magnetron sputtering nor by more advanced methods, including High Target Utilization Sputtering (HiTUS). Therefore, the aim of the current project is the investigation of of the formation of two/multi-phase boride-carbide structures stabilized by high entropy in the multielement ceramic coatings based on transition metals using reactive HiTUS. At first, the depositions of single-phase TM borides and carbides will be investigated during rHiTUS. In the second stage, both processes will occur within one step. It allows us to consider the peculiarities of oech process and find out corresponding ways to control the formation of structure of the dual/multi-phase ceramic coatings. The novelty of the project is that it widens the existing bulk two-phase ceramic materials into the field of PVD coatings and brings new ways to control their design and properties via the application of a novel HiTUS technology. |
