Course detail

Recovery and Surface Treatment

FSI-HPUAcad. year: 2024/2025

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

Rules for evaluation and completion of the course

The final exam will be composed of written and oral part. It is classificated to the ECTS grading scale.


Attendance at exercises is compulsory. Absence may be compensated for by the agreement with the teacher who can set a special programme to be worked out.

Aims

The main objective of the course is to provide students with the theoretical foundations and methodology necessary for solving technologies of renovations and surface treatment. Students will acquire knowledge necessary for a creative and complex solution of renovations and surface treatment.


The students will acquire knowledge of all types of modern technology cladding and surface treatment. They will be able to apply these technologies to the machine construction manufacturing.
