Vybrané vlastnosti oceli 19663 po různých typech povrchového zpracování

Abstract

The work is aimed at an analysis of properties of 19663 tool steel after various surface treatment types and finding the optimal variant of heat treatement. For this purpose, micro-purity evaluation, microstructure study using optical microscopy and scanning electron microscopy and micro-hardness testing HV0.2 were carried out. For the selected alternatives, the HV1 hardness test was also carried out and the tribological properties of the material were tested. The highest microhardness was detected in material quenched using laser, while material nitride with thicker layer and subsequently conventionally quenched showed the best tribological properties.
