    Vplyv technológie tepelného spracovania na tribologické vlastnosti vybraných oceľových materiálov
    (University of Žilina, 2024) Harvanec, Jakub; Mičian, Miloš; Nový, František
    The heat treatment technology changes all sorts of materials properties. We examined the change of tribological properties of selected powder metallurgy materials and conventional steels, in this article. We used special testing equipment, for measuring the changes of friction coefficient of individual tested materials, before application of the heat treatment and after application of the heat treatment. We tested two types of powder metallurgy steels and two types of conventional steels. The changes in friction coefficient are shown in the table and charts. We used boronising, nitriding and surface hardening as procedures of heat treatment.

    Vyvolanie scitlivenia na koróziivzdornej oceli 1.4845
    (University of Žilina, 2023) Kaličiak, Samuel; Kantoríková, Elena; Bolibruchová, Dana
    The experiment is focused on the influence of heat treatment, solution annealing and subsequent sensitization of stainless steel 1.4845. In the experiment, a suitable thermal cycle of solution annealing and subsequent sensitization is designed. Subsequent comparisons of the microstructure and hardness of steel 1.4845 before and after the proposed heat treatment

    Dodatočné spracovanie spekaných materiálov
    (University of Žilina, 2023) Kantoríková, Elena
    Powder metallurgy is a method of producing materials and products with required properties and required exact shapes. The development of new materials contributes to this. The general advantage of powder metallurgy is the possibility of producing parts of complex and precise shapes in large series and optimized production costs, resulting from lower energy requirements compared to casting and chip machining.
