Learning outcomes
The formation of micro and nano coatings on the surface of technical materials is one of the fields that affects all branches of engineering production. For this reason, more and more attention is paid to understanding the basic laws, properties of surfaces and the possibilities of improving technologies, methods of preparation and protection of these surfaces. One of the conditions is to get acquainted with the processes that take place on the surface of the material in contact with the defined surrounding environment and its effect on the properties of the material. Based on this, it is possible to design the surface treatment of the material and select the technology of forming a surface layer or coating that meets the given conditions and creates suitable surface properties in connection with extending the life and quality of the treated surface. Course contents: 1. Surface and its properties - surface structure, physical properties of the surface, geometric and mechanical properties of the surface, chemical properties of the surface, adhesion, cohesion, diffusion layers, etc. 2. Surface characteristics of technical materials - properties of metals at the phase interface, ideal crystal surface, surface microgeometry and the effect of surface preparation, the relationship between surface and coating, etc. 3. Physics of phase interfaces - metal-gas phase interface, metal-electrolyte phase interface. 4. Surface failure, the importance of physical properties of surfaces and their evaluation. 5. Methods of surface protection - environmental treatment, choice of suitable material and surface treatment, design solutions and production technology, electrochemical and temporary protection. 6. Preliminary surface treatments - mechanical surface treatments, chemical surface treatments. Electrochemical surface protection (anodic and cathodic) 7. Inorganic coatings - chemical electroless plating, electrolytic (galvanic) plating, plating in molten metals, diffusion plating, thermal spraying, plating (explosion, rolling), etc. 8. Surface treatment of Al material by anodizing and defects on anodized surface, other technologies of coating Al alloys (powder coatings, anodic coating, etc.). 9. Micro and nanolayers - description, identification, properties, basic preparation technologies, thin film diagnostics. 10. Formation of layers by chemical means - chemically formed microlayers and more layers, nano and micro composite coatings, coatings based on liquid matrix with addition of nano and microparticles, geopolymer layers etc. 11. Physical methods of vacuum coating - PVD layers, hybrid coating plasma pulax, vacuum evaporation and sputtering, magnetron sputtering, ion plating, LARC technology. 12. Chemical methods of vacuum coating - CVD. 13. Ion implantation of the surface of metallic materials, laser deposition of surfaces of metallic materials, coating by laser ablation of multicomponent materials.
