Minimalizace abrazivního opotřebení pomocí tvrdokovových návarů u zemědělských strojů
 Bednář, Štěpán
The preparation and processing of land is the primary process in agricultural practice, which leads to the provision of the basic needs of mankind. The operation of racks and machine parts is exposed to negative aspects in these conditions. Tribological influences associated with operation have an impact on the mechanisms of functional parts and cause their abrasive wear. This work deals with the minimization of abrasive wear using carbide welds. Detailed information on the mineralogical properties, size and shape of abrasive particles is summarized in the theoretical part. The chapter also describes the types of materials, heat treatment and welding technology. After that, the characteristics of agricultural machines and machine parts with increased intensity of abrasive wear and methods of renovating parts are described. The experimental part describes the preparation of samples by the fusion welding method and the analysis of the weight loss of the material on the sanding cloth. Using the results, the mechanical properties of the applied carbides are then evaluated.

Degradační procesy u strojů pro zpracování půdy
 Kubík, Petr
The diploma thesis is focused on degradation processes in machines tillage. The main intention of this thesis is monitoring and comparing abrasive wear of current technical materials. Wear is evaluated by using weight decrease at operational and laboratory test. In the theoretical part is processed basic division machinery for tillage, description of the particular degradation processes focused on abrasive wear of agricultural machinery. The practical part is focused on describing particular technical materials. It describes the production of test specimens and their heat treatment. Followed by operational and laboratory tests. The obtained results can recommend suitable material that can withstand the best abrasive wear and ensure functional as optimally sharp cutting edge.
