Surface hardening os steels by YbYAG fiber laser
 Hromada, Martin ; Daněk, Ladislav (referee) ; Mrňa, Libor (advisor)
Diploma thesis is focused on laser hardening by Yb:YAG fiber laser. Experiment is based on hardening of testing pieces made of steel 12 050 with different parameters of distance and movement speed of laser head. In theoretical part are described principle of laser, types of lasers, laser technology in industry, types of lasers, types of hardening and types of hardness measuring. In practical part are firstly evaluated macrostructure and microstructure photos and Vickers hardness. In conclusion are analyzed the results of laser hardening and after that the best laser hardening parameters were selected.
