Quality evaluation of unprocessed steels for corrosion
Holubářová, Michaela ; Buchtík, Martin (referee) ; Doskočil, Leoš (advisor)
This bachelor thesis is based on quality evaluation of unprocessed steels for corrosion. Visual control of the steel quality by a microscope is not sufficient, as this method of resistance assessment lacks quantified values. Current instruments are already able to provide specific corrosion values and therefore the SmartCET has been used to electrochemically characterize the supplied steel materials. The theoretical part includes general description and basic division of steel and corrosion. It also contains a summary of thermodynamic and kinetic corrosion aspects and methods of metal resistance evaluation. The experimental part deals with the measurements and evaluation of electrochemical characteristics (general corrosion rate, pitting factor and B value) over time compared to visual control.

Production of the upper part of gasoline tank
Minář, Martin ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of the upper part of the gas tank. Taking into account the shape and dimensions, the solution was chosen the most advantageous drawing technology without a thinning of 1 mm thick DC04 steel. The solution took account of the requirements of the contracting authority and selected the production for one operation. However, the simulation proved inappropriateness of the solution, so the procedure was modified to two operation proces. At the first stroke, a larger part of the body will be created, and in the other, a calibration of the cut-out dimensions will occur. For the first operation, the design of the tool kit, including drawing documentation for the CTH 250 press, was elaborated.

Production of anemostat
Bíba, David ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The thesis handle design of part of anemostat in size of series 15000 pcs/year. Due to conus shape and dimensions of part was chosen out of quantity of manufacturing processes a technology of deep drawing without a thinnig of 1mm thick DC04 steel. The resulting solution is progressive tool which concatenate four operations of deep drawing process. The drawing tool make use of standardised components. The design contain progressive tool including drawing documentation. Hydraulic press CTH 400 with nominal force 4000 kN is used for mentioned procedure.

Manufacturing of the engine oil tank cap
Polášek, Lukáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The project introduces a technology design of an oil tank cap manufacturing for a turboschaft engine TV3 – 117MT of the MI – 17 helicopter. The component will be produced of DC04 material in a batch of 10 pieces per year. Based on the evaluation of possible production methods the rubber pad forming process with an uncertain instrument (Guerin Method) was chosen. A raw material of 112 mm diameter will be cut out from a metal sheet which dimension will be 1000 mm x 2000 mm x 1 mm. An versatile (universal) tool which is suitable for forming, cutting and bending is designed for a hydraulic press machine CTH 1000. It`s power is 10 000 kN and it is available in the Arial toolshop.
