Course detail
FSI-9EHDAcad. year: 2024/2025
The subject provides theoretical and practical knowledge regarding processes of friction, lubrication and wear which take place in machines with essential importance in its research, development and production. Attention is paid on student’s understanding of basic and advanced principles and its application to research and development of tribological systems. The subject follows up and complements content of subjects in the Master’s study in the fields of tribology, mechanics, mechanical engineering and material sciences.
