The research of hard protective coatings is distictively application-oriented, as the main goal is to increase the lifetime of tools in the machining environment. Optimal combination of properties required for hard coatings can only be achieved by an in-depth study in several levels: understanding the process of coating growth, analysis of influence of deposition parameters on coating properties, and analysis of coating wear processes. The topic is distinctively interdisciplinary, encompassing plasma physics, physics and chemistry of surfaces, metallurgy, materials science and mechanical engineering. Beside a targeted development of a coating for specific technological application, the study of above mentioned processes contributes to a general knowledge of deposition and application of hard coatings. The most important materials for hard coatings are transition metal nitrides, but the department is doing research on other materials such as diamond-like coatings, quasicrystals, oxides, etc. The emphasys of characterisation is in mechanical properties, such as micro- and nanohardness, and adhesion. This is not exclusively limited on hard coatings, as we measure these properties on other types of thin films too. Some of the techniques can also be applied for surfaces of bulk materials.
