Original abstract
Protective layers are used to improve high temperature performance of structural materials. However, the effect of coatings on mechanical and fatigue properties is not sufficiently known because it is a combination of many factors as high-temperature exposure time, thermal cycle and coating deposition technique. Interactions between the coating and the substrate under high-temperature conditions influence the life time of coated blades. This paper is focused on the study of microstructure and properties of aluminide protective layers deposited on cast polycrystalline nickel base superalloy Inconel713LC. The light microscopy with image analyses and scanning electron microscopy with energy dispersion spectroscopy were used. The surface treated specimens exposed at 800 degC in air and cylindrical specimens with protective layer cyclically loaded under strain control at 800 degC in air were studied. Experimental data on thickness, uniformity and chemical analysis of individual phases are obtained for as-coated specimens, for specimens exposed to 800 degC for 500 hours in air and for specimens fatigued to fracture at 800 degC in air.
Czech abstract
Ke zlepšení užitných vlastností konstrukčních materiálů za vysokých teplot se v současnosti používají zejména ochranné vrstvy. Aplikací povlaků dochází ke změnám mechanických vlastností vzniklého kompozitu v porovnání se základním materiálem. Tyto vlastnosti ovlivňuje doba teplotní expozice, teplotní cyklus, typ povlaku a jeho výroba, chemické složení povlaku apod. Tato práce je zaměřena na studium mikrostruktury a vlastností ochranné vrstvy nanesené na povrch polykrystalické superslitiny na bázi niklu Inconel 713LC. Jako experimentální technika byla použita světelná mikroskopie s obrazovou analýzou, skenovací elektronová mikroskopie s EDS. Válcové vzorky s povrchovou úpravou, které byly tepelně zpracovány při 800 st C na vzduchu a bez povrchové úpravy byly zatěžovány střídavým souměrným cyklem tah-tlak při 800 st C na vzduchu v režimu řízené deformace. Rovněž byly metalograficky studovány vzorky po tepelné expozici na 800 stC po 500 h.
