Item Ochrana kovových materiálov pred chemickým vplyvom prostredia pri ohreve(University of Žilina, 2025) Kantoríková, ElenaProtecting metal components from chemical influences during heat treatment is important due to corrosion, where metals can react at high temperatures and subsequently weaken the component. Due to oxidation, metals can oxidize, meaning they react with oxygen in the air. This process can create oxide layers that can be brittle and peel off, exposing fresh metal that can further oxidize. Chemical reactions can change the structure of the metal, leading to its weakening and increased susceptibility to mechanical damage.Item Vplyv teploty formy na vybrané vlastnosti AlSi5Cu2Mg(University of Žilina, 2024) Kantoríková, ElenaCurrently, high demands are placed on the costs associated with the production of products, therefore it is advisable to know the individual characteristics of materials that are used in industry. The article deals with the influence of mold temperature on the mechanical properties of aluminium alloy. By knowing the characteristics of individual materials, it is possible to effectively design and manufacture equipment that will be safe and suitable for the given application. In many cases, aluminium alloys are offered as a solution, which are considered innovative construction materials, mainly because of the perfect combination of their properties.Item Kovokeramické trecie materiály využívané v práškovej metalurgi(University of Žilina, 2024) Kantoríková, ElenaMetal-ceramic materials are produced from a mixture of metal and ceramic powders. These are primarily sintered carbides for cutting tools and friction materials for brake linings. Their use is important in cases where it is not possible to use normal friction materials. Important is a high coefficient of friction even at high temperature, good thermal conductivity, strength and resistance to abrasion.Item Materiály práškovej metalurgie(University of Žilina, 2024) Kantoríková, ElenaPowder metallurgy is used in all branches of industrial production. the main advantage of powder metallurgy is the saving of metals (materials) and energy. the main direction of development is expected mainly in the production of tool parts. the article describes the analysis of powders and the use of materials for powder metallurgy.Item Materiály s vysokou teplotou tavenia využívané v práškovej metalurgii(University of Žilina, 2024) Kantoríková, ElenaMetals with a high melting point are frequently used materials in technical practice. Their fundamental advantage over other metal materials is their higher melting temperature, which exceeds the melting temperature of iron. Thanks to this physical property, such metals and their alloys can be used in environments where the components are subject to high thermal stress.Item Vyvolanie scitlivenia na koróziivzdornej oceli 1.4845(University of Žilina, 2023) Kaličiak, Samuel; Kantoríková, Elena; Bolibruchová, DanaThe 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 treatmentItem Vplyv vysokej prevádzkovej teploty na funkčnosť ložísk(University of Žilina, 2023) Kantoríková, ElenaRolling bearings are among the most important parts of machines and equipment. Many malfunctions in operation can be prevented by the correct choice of bearing, regular inspection and maintenance. The failure rate of the bearing is affected by many factors such as inappropriate storage, incorrect assembly, intrusion of foreign particles into the bearing spaces, inappropriately selected lubricant, or incorrect handling, transportation, etc. If damage or other deficiencies occur in rolling bearings, it is important to determine the cause of the damage so that appropriate measures can be taken to prevent their recurrence. Incipient damage to the bearing is reflected in the operation of the bearing, usually by a rise in temperature, or an increase in noise and stronger vibrations.Item Disperzne spevnené materiály(Žilinská univerzita v Žiline, 2023) Kantoríková, ElenaDispersion reinforced systems are composites with a matrix reinforced with a dispersive discontinuous phase. They are mainly produced by powder metallurgy technologies. Dispersion-strengthened materials have a polycrystalline matrix, into which dispersed particles are introduced, most often of the type of oxides, carbides and nitrides. The essence of the strengthening effect of dispersoids is both direct and consists in inhibiting the movement of dislocations of the matrix, as well as indirect in that, during the formation of the system, dispersoids increase the density of dislocations and refine the grain and subgrain structure.Item Dodatočné spracovanie spekaných materiálov(University of Žilina, 2023) Kantoríková, ElenaPowder 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.Item Technológ 3/2022(Žilinská univerzita v Žiline, 2022) Sýkorová, Martina; Bolibruchová, Dana; Bílik, Jozef; Sobota, Róbert; Šuba, Roland; Mojžiš, Milan; Litvaj, Ivan; Dižo, Ján; Blatnický, Miroslav; Ishchuk, Vadym; Molnár, Denis; Štaffenová, Katarína; Rakyta, Miroslav; Bubeník, Peter; Biňasová, Vladimíra; Kasajová, Marta; Tarbajovský, Pavol; Puškár, Michal; Абович Подригало, Михаил; Петрович Кравченко, Александр; Герлици, Юрай; Сергеевич Шеин, Виталий; Сергеевич Ткаченко, Александр; Александровна Кравченко, Екатерина; Kantoríková, Elena; Koňár, Radoslav; Matejka, Marek; Podprocká, Radka; Kostrzewski, Mariusz; Jerzy Nowak, Wojciech; Medňanský, Martin; Brůna, MarekVplyv teploty precipitačného vytvrdzovania na vlastnosti zliatiny AlSi5Cu2Mg legovanej Zr || Seamless Tubes Manufacturing Processes Analysis || Decision-making process and knowledge management, knowledge management and skills || Nákladné prívesy za traktor - koncepčné usporiadanie a ich typy || Proces reverzného inžinierstva s využitím 3D laserového skenovania || Nákladné prívesy za traktor - špeciálne verzie a zvláštna výbava || Knowledge, knowledge management and innovations || Návrh modelu parného rušňa || Integrovaný systém pre redukciu emisií spaľovacích motorov || Technical preparation of production || О выборе мощности двигателя автомобиля на этапе проектирования || Vplyv tepelného spracovania na nástrojové ocele || Skúsenosti pri ultrazvukovom skúšaní zvarov v praxi || Hodnotenie tepelného zaťaženia vysokotlakovej formy pomocou numerickej simulácie || Rzeczy kilka o transporcie kolejowym ładunków w Japonii || Precipitačné vytvrdzovanie Al-Si-Cu-Mg zliatin || Numerické simulácie vplyvu technologických faktorov na štruktúru vysokotlakových odliatkov
