The course deals with surfaces layers, their physical, chemical, mechanical and other characteristics. It provides information about possible surface finishing, both mechanical and chemical. The course then covers the various of thin layer depositions. Both classic methods (CVD,PVD) and advanced methods (IBAD) are detailed described. Besides that, the course informs students about different types of layers, and compares their properties. Moreover the thin layers evaluation methods is analyzed, together with the possibilities and restrictions of its methods.


Basic knowledge of the fundamental courses Physics I, Physics II. Knowledge of the basic technology is an advantage.

Study Objective:

The main purpose of the subject is to provide students information about basic theories of physical surfaces layers , and to give fundamentals of issues concerning thin layers and their applications in different areas of industry, particularly of in mechanical engineering. The aim of the study is to provide students with advanced knowledge of the subject, which can be applied in their career. More specifically, the students should be able to propose the optimal surface layer for a given engineering application, as well as specify its production technology.
