Optimization of surface pretreatment of steel and aluminum alloy for subsequent application of powder paint
Běloch, Martin ; Březina, Matěj (referee) ; Wasserbauer, Jaromír (advisor)
This diploma thesis deals with various procedures of surface pretreatment of steel and aluminum alloy for subsequent application of powder coating substance. The work begins with an overview of the general characteristics of the materials used. The core part of the work is then a summary of the individual methods of pretreatment that can be used to modify the material surface. A special chapter is devoted to methodologies for the application of powder substances. Before separate application, the sample must first be carefully pretreated to ensure removal of organic compounds (e.g. oils from primary processing - grinding, cutting), or dust impurities to ensure the correct barrier effect. After dividing the individual methods of surface preparation, a powder paint system with a total thickness of approximately 50 µm is applied to the test material. Samples with different surface pretreatments will be compared both in terms of mechanical properties and in terms of electrochemical properties.

Vliv mimokořenové výživy na technologickou kvalitu cukrovky
Běloch, Martin
This Bachelor thesis deals with the influence of non-root nutrition on the technological quality of sugar beet. The first part of this thesis is focused on general facts. This section discusses the origin of sugar beet, its botany, agriculture technology, fertilization, establishment, control of diseases and pests including control of weeds. Additionally, this section includes information about chemical composition and technological quality of the tubers and their subsequent use. In the practical part, the small field attempt was established, in which the influence of nonroot nutrition of sugar beetis tested on the technological quality of the tubers.
