Subject aims expressed by acquired skills and competences
- graduates will acquire a comprehensive knowledge of the major systems and processes in which the surface of the material play an important role,
- will be able to explain how we can modify the surface of the material to optimize its properties, including increased resistance to degradation processes,
- students will be able to determine or evaluate the parameters and characteristics of the micro-geometry surface, and discuss the surface-active substances.

Summary
The course discusses the important physical, chemical, mechanical and other aspects of surfaces. Content is focused on the characteristics and structure of surfaces, thin films and coatings. It deals with surface treatments and methods of testing properties of surfaces. The inner surfaces (interfaces) are gaining importance for very fine and nano-structured materials.
