Utilization of cold spray technology for ballistic applications
Kuník, Adam ; Doubrava, Marek (referee) ; Řehořek, Lukáš (advisor)
The goal of this bachelor's thesis is to get familiar with cold spray technology, as an alternative in the field of both coating application and, among other things, its use for the repair of some parts with complex shapes within additive manufacturing. It then coveres the basic principles of this method, the metal powders used, the characteristics of the device, familiarization with the issue of ballistic protection and terminal ballistics. In the second, experimental part, the quality and mechanical properties (especially the hardness, porosity, and coating thickness) of this layer produced by the above-mentioned method, as part of ballistic protection for light armored vehicles, are evaluated.

Influence of Process Parameters and Heat Treatment on the Structure and Properties of Cold Spray Method
Lindner, Patrik ; Řehořek, Lukáš (referee) ; Hutařová, Simona (advisor)
The bachelor thesis is a research of the state of knowledge focused on Cold spray technology and process parameters affecting the properties of coating, such as pressure, temperature, nozzle speed, sequence of individual layers, size of powder and others. This technology uses the kinetic energy of the impact of particles on the substrate. The main advantage of this method is possibility of forming a coating of large thicknesses (in millimeters) without oxides, with relatively low porosity and favourable mechanical properties. Aim of this work is to get acquainted with the Cold spray technology and the influence of process parameters on the quality of the spray. The influence of process parameters on properties is also demonstrated by own experimental results.
