Annotation Diplomová práca rieši problematiku tepelného ovplyvnenia ocelí pri delení materiálu lase-rom. V priebehu delenia materiálu laserom dochádza k jeho intenzívnemu tepelnému ovplyvneniu a tým aj ovplyvneniu tvrdosti povrchovej vrstvy . V teoretickej časti je popí-sané základné rozdelenie ocelí, spôsoby delenia materiálu, meranie tvrdosti a mikrotvrdosti. V praktickej časti sú štatisticky spracované a následne vyhodnotené namerané hodnoty. Vplyv tepelného žiarenia na zmenu tvrdosti zadaných materiálov v mieste rezu je skúmaný pomocou merania mikrotvrdosti a to metódou podľa Vickersa.
Annotation in English This thesis studies issues related to thermal influence of steel caused by splitting the mate-rial by laser. In the process of splitting the material by laser, intensive thermal influences occur, affecting hardness of the surface layer. In the theoretical part, main classification of steels, different methods of material splitting and methods of measurement of hardness and microhardness are described. In the practical part of the paper, measured data are statistically processed and evaluated. The effect of thermal radiation on the change of hardness on section cuts of studied materials is examined through measurment of microhardness according to the Vickers method.
Keywords Rozdelenie ocelí, Metódy delenia materiálu, Tvrdosť, Mikrotvrdoť, Vickers, Knoop
