Course detail

Recovery and Surface Treatment

FSI-HPU-KAcad. year: 2018/2019

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.

Learning outcomes of the course unit

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.

Prerequisites

Basic welding technologies - flame, arc welding, plasma, laser. Thermally and deformation field, weldability of materials, inorganic chemistry, corrosion.
