In particular, students will know:

• the fundamentals of physical vapour deposition (PVD) thin film technology especially on coating deposition and coating characteristics
• process-specific features and differences as well as process-related coating properties
• the innovative and industrially established analysis methods from plasma diagnostics to tribological testing
• application-oriented process and coating material selection as well as coating deposition

After successful participating in the module course, students are able to describe typical coating processes of PVD thin film technology, explain the process-specific advantages and disadvantages as well as the limitations of the processes and coating systems, describe the areas of application of different coating systems and materials and list typical application examples.

Students will be able to understand the use and selection of different PVD coating processes and coating materials for application areas, general mechanical engineering, production and manufacturing technology, energy technology, automotive and aerospace technology and medical technology.
