Assessment of corrosion degradation in materials
Plichta, Lukáš ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
The work describes the principle of degradation of corrosion in materials, specifically metals and their alloys. Corrosion is divided into several aspects. The fundamental division according to its origin divides this phenomenon into chemical, electrochemical and biological corrosion., It distinguishes between uniform, non-uniform, spot, selective, crevice, erosive, intercrystal corosion and corrosion cracking according to corrosion damage. It also presents corrosion testing options. In the experimental part, it describes the production of samples from gray cast iron, their dimensions, applied surface protection, hardness measurement and roughness measurement. This work also conducts electrochemical tests and tests in a condensation chamber on selected samples of gray cast iron GJL-250MnCuCr.

Monitoring the condition of a lead-acid battery used in automobiles
Folk, Jan ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
The aim of this bachelor thesis is to test the properties of lead-acid batteries according to the ČSN standard. The work deals with test methods on a lead-acid battery, which examines the life test, charging current test and reverse capacity test. Furthermore, the work deals with the thermal loading of the lead-acid battery under extreme conditions that may occur during transport. The lead-acid battery transport will be simulated using the Solidworks modelling program and the Ansys simulation program.

Evaluation of cold kinetic deposition technology (Cold Spray)
Buček, Tomáš ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
Cold spray or Cold gas dynamic spraying is actually new process for coating application. Origin of Colds technology spray is thermal spray. Cold spray technology has some advantages therefor any other common thermal technology. Cold spray technology has unique properties mainly due to low deposition temperatures and the physical principle of layer growth. Master’s thesis has focused on the possibility of use for corrosion protection. Accelerated corrosion tests were performed in a condensation chamber with samples of aluminium substrate and low pressure cold sprayed copper layer. The formation of corrosion was evaluated by acoustic emission and metallographic analysis. The anti-corrosion properties of copper have been considered in practical design, as have the unique antibacterial and virus inactivating properties.

Evaluation of the use of non-destructive methods of acoustic emission on materials
Vašíková, Simona ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
This master thesis is about acoustic emission itself and acoustic emission as a nondestructive method of testing materials. There are different types of metal materials corrosion too. In this thesis is possible also find corrosion protective methods. There are practical examples of use the acoustic emission method at metal materials corrosion from automotive, aviation, food processing and manufacturing industry with construction and civil engineering examples. The experimental part is focused on samples preparing and measuring the acoustic emission signals during continual corrosion process of grey cast iron in condensational corrosion chamber. These results are supported and completed with metallographic analysis.

Implementation of Industry 4.0 technologies in the warehouse
Fabián, Jan ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
In the first part of this master’s thesis. the current technologies used in smart warehouses were discussed with the use of a literature survey on the Industry 4.0 and the role of warehouses in the modern-day supply chain. This part is followed by an analysis of technologies and processes in an army warehouse. This analysis was used to design an automated solution for this warehouse based on the principles of Industry 4.0. Current state and automated solution were compared using AHP method. In the end, design of a photovoltaics system with accumulation to serve as a back-up in the case of blackout is also proposed.

Design of a kit for the creation of a supply point for electricity generated from renewable sources
Fridrich, Jiří ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
This project deals with the design and realisation of a set that will work as a power supply point with electricity generated from renewable energy sources. The theoretical part deals with information about renewable energy sources and energy storage options. In the practical part, a mobile kit for powering variable message traffic signs is designed. It uses photovoltaic panels and stores energy in a lead-acid battery. A methanol fuel cell is used for backup power. The device is adapted for use in road traffic and meets the requirements of the relevant authorities. To verify the stability of the structure, there were performed static calculations, which proved the ability of the device to withstand wind stress. Part of the work was to draw a complete production documentation, which was used to create a test sample. Long-term measurements of energy flows in the system were performed on that sample. These measurements confirmed the ability of the device to operate autonomously and the possibility of using it for the required purpose.

Use of cold kinetic deposition technology on materials used in electrical engineering
Sámel, Maroš ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
The purpose of this diploma thesis is to get a better understanding of cold kinetic deposition (cold spray), principles of functioning of this method followed by an evaluation of advantages and disadvantages of cold spray and its comparison to conventional thermal methods and a simple summary of the practical use of cold spray with respect to different materials. Next there is a summary of the properties and uses of frequently applied metals in electrical engineering, aluminium and copper, description of metal corrosion and an understanding of the diagnostic method of acoustic emission. In the practical part, a sample with copper cold spray coating on aluminium substrate was created. Following, this sample was split for corrosion tests, where the split samples were exposed to a corrosive environment for different times of exposure. The extent of corrosion degradation of the samples was evaluated by acoustic emission and metallographic analysis for corrosion-loaded samples for 100, 200 and 300 hours. In the end, an illustrative design of the application of the cold spray technology was created.

Use of 3D printing technology for the design of spare parts production
Šafl, Pavel ; Zimáková, Jana (referee) ; Binar, Tomáš (advisor)
This seminar thesis deals with the issue of 3D printing in companies. The aim was to describe additive manufacturing and 3D printing technologies. Moreover, to select the most common materials which are used and describe them. It was also necessary to perform a study of mechanical stresses and prepare a detailed description of the mechanical properties of materials. From these data, methods of use in the automotive industry were described. The most important part was to introduce case studies and create a description of which 3D printing technologies have the fastest return on investment.
