Manufacture of cast Early Middle Age Viking Weapon parts
Brůža, František ; Mareček, Petr (referee) ; Záděra, Antonín (advisor)
The Bachelor’s project is concerned with the research and the following analysis of information and the period technologies needed for making a replica of the brass hilt of a 10th century sword. The project particularly focuses on the period casting technology. Next, the possibility of making a replica by a 3D scan and 3D print is discussed. The project also includes a comprehensive experiment consisting of casting parts of the hilt using the period technology. The functionality reproducing the hilt by 3D technology up to the printed model stage is also tested.

Influence of sand size of core mixtures on surface quality of cast iron castings
Brůža, František ; Krutiš, Vladimír (referee) ; Záděra, Antonín (advisor)
The diploma project deals with the mechanisms of burn-on casting defects on castings made of spheroidal graphite cast iron. It discusses the elimination of their occurrence in the conditions of the German foundry MAT Ueckermünde by changing the granulometry of the core sand. Subsequently, the thesis deals with the influence of this change on the greensand. Furthermore, the thesis compares three refractory coatings supplied by the foundry. The coatings are compared both by laboratory measurements and by experimental tests during casting in conditions simulating the operation of this foundry. Finally, the individual tests are evaluated, including the effect of the individual measures in the case of their use in MAT Ueckermünde.
