Abstract
Tato diplomová práce se zabývá porovnáním tribologických vlastností vzorků vyrobených z materiálu Inconel 718. Vzorky byly zhotoveny pomocí tváření a 3D tisku metodou SLM. Vzorky byly navíc plazmově nitridovány.V teoretické části práce jsou popsány niklové slitiny s detailnějším popisem slitin Inconel. Dále popis nitridace s podrobnějším zaměřením na plazmovou nitridaci. Závěr teoretické práce je věnován tribologickým zkouškám s detailněji popsanou metodou Ball-on-Disc.Cílem experimentální části bylo stanovit, jaký má plazmová nitridace vliv na tribologické vlastnosti materiálu Inconel 718. Pro tribologické zkoušky bylo využito metody Ball-on-Disc, což sloužilo pro vyhodnocení třecích vlastností a odolnosti povrchu materiálu vůči opotřebení. Toto měření probíhalo při pokojové teplotě a za zvýšených teplot.
The aim of this diploma thesis is to compare tribological properties of specimens made of Inconel 718 material. The samples were produced by forming and 3D printing using SM method. In addition, the samples were plasma nitrided.In the theoretical part of the work, nickel alloys are described with a more detailed description of Inconel alloys. Furthermore, a description of nitriding is given with a more detailed focus on plasma nitriding. Finally, the theoretical work is devoted to tribological tests with a more detailed description of the method Ball-on-Disc.The aim of the experimental part was to determine the effect of plasma nitriding on the tribological properties of Inconel 718.The Ball-on-Disc method was used for tribological tests, which was used to evaluate the frictional properties and wear resistance of the material surface. This measurement was carried out at room temperature and at elevated temperatures.
