Based on the characterization of the structure and properties of surfaces, the challenges posed by tribological and corrosive loads are addressed and suitable methods for a suitable improvement of technical surfaces are discussed.

1. Structure and properties of surfaces
2. Tribological load
3. Corrosive load
4. Coating processes
   • Electrochemical metallization
   • Conversion processes (anodizing, ...)
   • Physical vapor deposition (PVD)
   • Chemical vapor deposition (CVD)
   • Hot-dipping
   • Thermal spraying
   • Cladding
   • Conversion processes
   • Diffusion processes
5. Mechanical surface modification
6. Surface texturing
7. Coating characterization
8. Aspects of environmental protection

Learning objectives

• Students can describe the typical processes (friction, wear, corrosion) that lead to surface damage.
• Students know methods for the defined production and characterization of material surfaces as well as methods for influencing surface properties.
• Students can select suitable materials and surface treatment processes for specific applications
• Students can evaluate the results of surface engineering investigations.
