Item Analýza tribologických vlastností kompozitného materiálu PA66+GF25(University of Žilina, 2025) Bronček, Jozef; Drbúl, Mário; Čuchor, Dávid; Madaj, RudolfThe aim of experiments was to acquire the knowledge that can be used in designing materials for bearing cages. The current trend is that leading bearing manufacturers are replacing metal cages in bearing construction with glass fiber (GF) reinforced polyamide (PA) cages. Experimental measurements were realized on the experimental device linear microtribometer working on the principle of method ball on plane. This method according to the standard ISO 7148-2 is standard method for tribological properties testing. The structure analysis of experimental samples was performed because of understanding of potential structure influence on material properties.Item Experimentálna analýza tribologických vlastností povrchov konštrukčných materiálov(Žilinská univerzita v Žiline, 2023) Bronček, Jozef; Vicen, Martin; Radek, Norbert; Bulko, TomášThe presented article deals with the tribological properties of the surfaces of structural materials. Comparing the results of experimental measurements of three different surfaces (chrome steel 100CrMnMoSi8-4- 6, blackened steel surface, DLC coating) and three different balls (chrome steel 100Cr6, silicon carbide, tungsten carbide) made it possible to observe the influence of the materials of the friction pair on the tribological properties.
