Studium vlivu předúpravy povrchu na mechanické vlastnosti povlaku

Abstract

This bachelor's thesis examines the effect of surface pretreatment on the mechanical properties of the resulting coated. The introduction of the thesis defines the concept of coatings and explains their composition, marking, and application. The thesis also deals with the formation and types of degradation of coatings. The second part of the thesis describes the mechanical and chemical pre-treatment of the basic material. In the practical part of the work, various pre-treated steel samples are coated with heat-resistant paint used on fireplace stoves and inserts. The final part of the thesis focuses on measuring the thickness of the dry layer and mechanical coated tests, such as the grid test and the tear-off adhesion test. Evaluation of experimental works is given in clear tables and graphs.
