Course detail
Recovery and Surface Treatment
FSI-HPU Acad. year: 2024/2025 Summer semester
The course Recovery and Surface Treatment is important for technologists and designers. It is based on the technology of:
- weld cladding: arc welding, flame welding, plasma and laser welding, inclusive of special techniques,
- thermal spraying by: arc, flame, plasma, high velocity methods (HVOF),
- surface treatment: surface theory, oxidation methods (eloxal process), electroplating Cu, Cr, Ni, Zn, etc. – – organic coatings
- bonding, cementation, adhesive, dispersion hardening.
All technologies will be accompanied with an overview of auxiliary materials, typical examples and industrial applications
