Influence of isothermal exposure on microstructural changes resulting in delamination of eutectic Al2O3+ZrO2+SiO2 thermal barrier coatings
Original language description
Eutectic ceramic Al2O3-ZrO2-SiO2 also termed Eucor (as a top coat) and CoNiCrAlY (as a bond coat) coatings were sprayed onto the surface of recently developed fine-grained cast polycrystalline nickel-based superalloy Inconel 713 LC by means of water stabilized plasma (WSP) and atmospheric plasma spraying (APS) techniques, respectively.Specimens were subjected to isothermal oxidation at 1050 °C for 10, 50, 100, 200 and 500 hours in ambient atmosphere,prior to which a half of the as-sprayed specimens wasannealed at the temperature of 950 °C for 10 hours.Influence of short-time and long-time isothermal exposure on interactions at the bond-coat/top-coat interface was studied.The uniform and continuous oxide layer,also termed the thermally grown oxide (TGO),was formed and grew at the bond-coat/top-coat interface in all samples, both with and without the heat pre-treatment. Relationship between the dwell time, heat treatment and TGO growth kinetics was quantified.Microstructural changes
