Syllabus of lectures:

Outline:

1.The enviromental action on surface. Categories of surface treatments and their history. Decorative layers and paints.

2.Surface modifications of material: surface preconditioning, grinding, polishing, blasting, shot-peening, etching, surface quenching, conversion layers, galvanic metallization, ladding, ion implantation, ...

3.Thin layers: PVD, CVD, Magnetron sputtering

4.Themal and cold spray – echnologies, proces parameters, proces diagnostics, materials applications

5.Application of coatings :(thermal barrier coatings, abrasion resistant and abradable coatings, corrosion resistant coatings, nuclear fusion materials, ...), biomedical coatings

6.The peculiarities of coating chracterization (stress-strain, microhardness, phase composition, porosity, functional properties)

7.Laboratory work and excursions (anodizing, basic characterization of selected coatings, visits to spray labs at IPP CAS, and surface modification companies)

8.Application seminar: students present the review of selected area of surface modification.
