Summary
The aim of the course is to improve knowledge of PhD students about structure and properties of material surfaces. The attention is paid to processes taking place at surfaces, interfaces and in thin layers. The special attention is paid to modern technologies of surface engineering, especilly plasma technologies and thermal coatings. Applications of the most important technologies are demonstrated on practical examples. Basic techniques of structure and property characterisation of material surfaces are discussed.
