Abstract
Inconel 713LC was developed in the 1950s and is still widely used in power generation especially because of favourable price in conjunction with satisfying properties. However, the need for higher efficiency of high-temperature facilities leads to increase operating temperature that causes severe degradation of the material. In order to enhance the life-time of material, the protective coatings are applied. For the purpose of this study, nineteen cylindrical specimens were cut from rods manufactured using investment castings technique and subsequently, 10 specimens were coated with novel complex thermal barrier coating (TBC) system. The TBC system comprises a metallic CoNiCrAlY bond coat (BC) and a complex ceramic top coat (TC). The TC is a mixture of conventional YSZ ceramic and a eutectic nanocrystalline ceramic Eucor in the ratio of 50/50 in wt%. Eucor is made of zirconia (ZrO2), alumina (Al2O3) and silica (SiO2). Low cycle fatigue tests were performed in symmetrical push-pull cycle under strain control at 900 °C. Cyclic hardening/softening curves, cyclic stress-strain curves and fatigue life curves of coated and uncoated material were obtained. Fracture surfaces and polished sections parallel to the loading axis of specimens in as-coated conditions and after cyclic loading were observed by means of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) to study degradation mechanisms during high-temperature low cycle fatigue. TBC delamination was observed at the TC/BC interface and rafting of precipitates occurred after high-temperature exposure. The microstructural investigations help discuss the differences in the stress-strain response and fatigue life of coated and uncoated superalloy.
