Course detail
FSI-HPUAcad. year: 2022/2023
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., chemical layers, PVD,CVD, organic coatings, - bonding, cementation, adhesive, dispersion hardening. All technologies will be accompanied with an overview of auxiliary materials, typical examples and industrial applications.
