Item Zmena mechanických vlastností vybraných materiálov aplikáciou povrchového kalenia(University of Žilina, 2024) Fabian, Peter; Jaššo, Martin; Pastirčák, RichardComparing the mechanical characteristics of steel used in the weapons sector to make barrels for short, small arms is the study's goal. The heat treatment of representative samples resulted in their hardening, surface hardening to a specific layer thickness, and tempering. It has not yet been thoroughly examined how the thickness of the hardened layer affects the modification of the mechanical characteristics of the chosen materials. Surface hardening is widely regarded as one of the methods for producing a resistant core and a hard surface on a component. Nonetheless, the overall material's mechanical characteristics alter in tandem with the layer's thickness. The outcomes of this study will also be useful for the induction heat treatment of other similar material components.Item Aplikácie difúzie v strojárskej výrobe(University of Žilina, 2023) Jaššo, Martin; Pastirčák, RichardThis thesis aims to explain the nature of the diffusion process and the importance of this process in the field of engineering production. The thesis contains information on the principles and mechanisms by which diffusion takes place, as well as on the environmental influences and factors that directly affect this process. The thesis concludes with a description of selected manufacturing and surface treatment processes used in mechanical engineering, the principal basis of which is diffusion.
