Materials for Securing Fixed and its Degradation
Pálka, Lukáš ; Molliková, Eva (referee) ; Němec, Karel (advisor)
This bachelor’s thesis covers an overview of materials used for mountaineering fixed protection manufacturing (current and earlier used materials). It also deals with degradation processes found in fixed protection used in mountaineering practice. It quantifies basic degradation processes appearing on mountaineering routes of sport and also of alpine disposition. The thesis also takes in consideration specific damage, occurrence and extent of which is difficult to predict. Then it shows a need for further research of characters of real geological and climatic conditions and corresponding choice of suitable materials and establish a uniform procedure for detecting defects.

The corrosion study of part aircraft at the site of spot welds in the salt spray environment
Němčíková, Eva ; Doležal, Pavel (referee) ; Pacal, Bohumil (advisor)
This bachelor’s thesis is focused on the corrosion study of part aircraft at the site of spot welds in the salt spray environment. The panel is made of sheet of aluminium alloy AlCu4Mg1, with surface coated with aluminium of purity 99,5 %, and of square shapes of alloy AlCu4Mg1, without coating. Square shapes are an angle cleat. The thesis deals with corrosion characteristics at the site of spot welds and in the area of contact between them. It deals with character of corrosion, frequency of occurrence and range of corrosive attack. From the data files were detected critical places of construction.
