  • Exquisite Energy Savings at Cold Metal Forming of Threads through the Application of Polymers 

    Píška, Miroslav; Sliwková, Petra; Vnuková, Zuzana; Petrenec, Martin; Sedláková, Eva (MDPI, 2022-03-08)
    One of the global problems today is energy—its production and distribution. As the human population grows, the consumption of energy rises simultaneously. However, the natural sources are limited, and so the focus on power ...
  • Experimental Determination of Continuous Cooling Transformation Diagram for High Strength Steel X155CrMoV12 

    Krbaťa, Michal; Majerík, Jozef; Barényi, Igor; Eckert, Maroš; Čep, Robert; Sedlák, Josef; Samardžić, Ivan (Hrvatsko Metalursko Društvo, 2022-01-10)
    The article is a result of investigations which deals with the phase transformations of tool steel X155CrMoV12. The experimental data obtained was used to evaluate the resulting Continuous Cooling Transform (CCT) diagram, ...
  • Dilatometric Analysis of Cooling Curves for High Strength Steel X155CrMoV12 

    Krbaťa, Michal; Majerík, Jozef; Barényi, Igor; Eckert, Maroš; Čep, Robert; Sedlák, Josef; Samardžić, Ivan (Hrvatsko Metalursko Društvo, 2022-01-10)
    The article deals with phase transformations and austenitizing behavior of the X155CrMoV12 tool steel. Dilatation analyses of a series of samples were performed at various cooling rates, chosen in the range from 10 °C/s ...
  • The design of a device for testing the tribological properties of knee endoprostheses 

    Dobrovolná, Lucie; Varhaník, Matúš; Sedlák, Josef; Polzer, Aleš; Studený, Zbyněk (UJEP, 2021-09-18)
    The presented paper deals with the design of a knee simulator that uses pin-on-ball configuration, ie cartilage and CoCrMo head. The translational motion consists of the cartilage and the rotating head when the load of the ...
  • Cyclic Fatigue of Dental NiTi Instruments after Plasma Nitriding 

    Bumbálek, Michal; Joska, Zdeněk; Pokorný, Zdeněk; Sedlák, Josef; Majerík, Jozef; Neumann, Vlastimil; Klíma, Karel (MDPI, 2021-04-23)
    This study investigated the possibility of nitride NiTi instruments using low-temperature plasma nitriding technology in a standard industrial device. Changes in the properties and fatigue life of used NiTi instruments ...

    This paper deals with material and dimensional bending analysis of bimetallic pipes with defined bending radii. Basic characteristics of selected nickel superalloys with analysis of Inconel 625 and 16Mo3 steel in terms of ...
  • Application of composite materials in sports optics 

    Kupčák, Radim; Zouhar, Jan (J. E. Purkyne University in Usti nad Labem, 2020-08-18)
    CFRP (Carbon Fiber Reinforced Polymers) are often used when designing parts that need to be stiff, light and thermally stable. These benefits are a big motivation to use CFRP in many applications, one of them could be ...
  • Application of Linear Optimization on Parameters of 3D FDM Print 

    Zemčík, Oskar; Sedlák, Josef (Strojarski fakultet u Slavonskom Brodu, 2019-07-25)
    Nowadays, a fused deposition modelling (also called “FDM”) belongs to one of the most widespread additive methods of 3D print. It allows producing both models for functional verification or casts and functional components. ...
