Course description

Proper surface engineering in terms of surface modification of materials by coatings or different chemical/physical surface treatment processes is a technologically very important area. The lifetime and performance of engineering products depend decisively on their surface condition. This is evident for example concerning the corrosion resistance of vehicle bodies and the lifetime for key components in energy conversion processes as well as the performance of electronics components.

 

The objective of the course Surface Technology is to provide a general overview of technologically important processes for surface modification or coating of metallic materials. The first part of the course covers fundamental aspects of corrosion, oxidation, wear and surface chemistry as well as advanced techniques for surface chemical characterisation (X-ray Photoelectron Spectroscopy for Chemical Analysis (XPS), Auger Electron Spectroscopy (AES), Secondary lon Mass Spectroscopy (SIMS) of materials. The second part of the course addresses the principles of metal surface treatment and the application of different processes including following items:

 

• Metal Surface Cleaning
• Metal Coatings
• Inorganic Coatings
• Organic Coatings/painting
• Chemical Vapour Deposition (CVD)
• Physical Vapour Deposition (PVD)
• Thermal Spraying
• Laser Surface Coatings
• Weld Overlay Coatings
• Surface hardening

 

The course includes 4h dedicated lectures, 8h scheduled tutoring and 8h of laboratory work. Everyone will also have a seminar assignment that shall be performed during the course of the course. All seminar assignments will cover problems related to surface engineering aspects in relation to high temperature applications.
