Repairs of high-strength steels using Cold Spray technology
 Krvač, Matěj ; Foret, Rudolf (referee) ; Řehořek, Lukáš (advisor)
This diploma thesis takes into account the possibility of repairing high-strength steels using coldspray method. The theoretical part is focused on the coldspray method, austenite transformation, bainitic steels and Rmat contact fatigue tests. In the experimental part evaluate the hardness, the structure of the supplied substrate. The hardness, adhesion and porosity of the test sprays are ranked. Furthermore, tests for contact fatigue are evaluated. Finally, the results of the experiments are summarized and measures are proposed to improve adhesion, or to continue this issue.
