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.
