High temperature low cycle fatigue behavior of cast superalloy Inconel 713LC coated with ZrO2 -SiO2 -Al2O3 nanocrystalline thermal barrier coating
Original language description
Cast polycrystalline nickel base superalloy Inconel 713LC is used for production of blades and discs of gas turbine engines that are subjected to repeated elastic-plastic loading in aggressive environments at variable temperatures. Thermal barrier coatings (TBCs) consist of thermally insulating ceramic top coat and of a metallic oxidation/corrosion-protective bond coat. They can prolong the component life particularly by a reduction of temperature gradient during heating and cooling. In the present work, the high temperature low cycle fatigue behavior of cast nickel-based superalloy Inconel 713LC in as-received state and coated with novel Al2O3-SiO2-ZrO2/CoNiCrAlY TBC system was studied at the temperature of 900 °C. The microstructure of the substratematerial consisted of dendritic grains with carbides and shrinkage pores. The average grain size was 0.66 mm. The novel TBC system consists of a (inter)metallic CoNiCrAlY bond coat and a eutectic ceramic, i.e. zirconia (ZrO2), alumina (Al
