Module 1. Many engineering materials working under severe cutting, stamping, or bearing conditions including humid and corrosive environments, as well as temperature fluctuation require a combination of chemical, mechanical, and tribological properties. Desired properties can be achieved in hard nanofilms based on carbides, borides and nitrides of transaction metals by alloying with additional elements such as Al, Si, Cr, etc. In the first part of the lecture different approaches towards the design and preparation of hard tribological nanofilms with other enhanced characteristics are briefly summarize. The second part deals with the main film characteristics: hardness, Young’s modulus and elastic recovery; tribological properties; thermal stability; high-temperature oxidation resistance; electrochemical characteristics, and cutting performance.
Module 2. At the beginning of the lectures some basic definitions are introduced. Then the main materials for biomedical applications, such as metals and alloys, ceramics, and polymers are briefly described. The main ideas for the selection of film compositions for more advanced biomaterials are proposed. An approach to design perspective multifunctional bioactive nanostructured films (MuBiNaFs) for metallic and polymer implants is also described. Chemical interaction versus micromechanical integration is considered.
