NANOSTRUCTURED Mo-B-C COATINGS

Popis výsledku v původním jazyce

Nanostructuring is a recognized way of preparing novel materials with properties significantly different from their bulk constituents. Nanocomposite thin films, multilayers and nanolaminates were proven in many cases to be superior to conventional protective coatings due to their improved fracture toughness and wear resistance. Moreover composite architecture is a step towards independent control of toughness and hardness. X2BC boron and carbon based nanolaminates exhibit a unique combination of high stiffness and moderate ductility. However their synthesis temperature above 800°C impedes effortless applicability as a coating system. This temperature can be substantially reduced by a suitable choice of preparation method. In this paper we report on microstructure and mechanical properties of Mo-B-C layers prepared by magnetron sputtering. DC magnetron sputtering was used to prepare 1-2 um thin layers on rotated hard metal and steel substrates with optional Mo interlayer.
