- ItemNedestruktivní měření hloubky a tvrdosti povrchově kalených vrstev(Technická Univerzita v Liberci, 2008) Růžička, Ondřej; Skrbek, BřetislavThis bachelor´s work is focused on problems of non-destructive methods of measurement of depth and hardness of surface hardened layers. There are performed proposals of these methods for characteristic machine components like camshaft or crankshaft. There were used principles of ultrasonic and magnetic non-destructive measurement.

- ItemPřípravek na topografii kalených a tvrzených vrstev nedestruktivními metodami(Technická Univerzita v Liberci, 2011) Růžička, Ondřej; Skrbek, BřetislavThe work for this diploma focuses on the topic and possibility of using non-destructive testing for the determination of topography of hardened layers of engine parts. To ensure repeated accuracy and reproducibility of measurement by these methods, a manual positioning preparation was designed and constructed to fix and position the measuring equipment and to precisely fit the measured engine part into position. For this work I used a cam-shaft from engine TEDOM as a typical engine part. Applying this method for regular daily checks in an engineering company, I also included a preliminary design of the computer operated automatic positioning preparation.
