STRUCTURAL STABILITY OF THERMAL BARRIER COATINGS PRODUCED BY THERMAL SPRAYING

Popis výsledku v původním jazyce

One type of functionally graded coating system is thermal barrier coating (TBC), where the combination of ceramic and metallic coating is used both to reduce the temperature and to increase oxidation and corrosion resistance of the substrate. TBCs usually consist of the top ceramic coating based on YSZ (ZrO2+Y2O3) and the metallic bond coating of M-CrAlY type, where M means Ni, Co or their appropriate combination. Electron beam physical vapour deposition (EB-PVD) or vacuum (VPS), low pressure (LPPS) or atmospheric (APS) plasma spraying techniques are most frequently used as a deposition method. Despite some requirements on the product shape simplicity, the air plasma spraying offers high productivity, sufficient quality and much lower production costs in comparison with the EB-PVD technology. The contribution deals with high temperature structural stability of TBCs of YSZ + NiCrAlY and YSZ + CoNiCrAlY types that were produced by air plasma spraying on the INCONEL 713LC polycrystalline nickel based superalloy substrate. Immediately after deposition, the specimens were exposed to temperature of 1000 C for 5-500 hours in the common ambient atmosphere. The changes in both microstructure and chemical composition were studied by means of scanning electron microscopy, energy dispersive microanalysis and image analysis methods.
