| 英文摘要 | Segregation and microstructural evolution at interfaces of thermal barrier coatings (TBCs) during thermal cycling were systematically investigated using scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy. The as-sprayed TBCs were thermally cycled between 1100 degrees C and ambient temperature up to 3000 cycles. Results show that phosphorus, sulfur, and yttrium co-segregate at the top coat (TC)/bond coat (BC) interface after 3000 cycles. The above co-segregation at the BC/substrate interface was delayed by 1000 cycles. Chemical components of thermally grown oxide (TGO) layers at both the TC/BC and BC/substrate interfaces change from O and Al to O, Al, Cr, Co and Ni as the thermal cycling proceeded. The corresponding oxides in the TGO layers evolved from alpha-Al2O3 to alpha-Al2O3, Cr2O3, NiO and spinel phases. Controlled by the element diffusion rate and selective internal oxidation, evolution of the thickness of the TGO layers followed a natural logarithmic law. (C) 2019 Elsevier B.V.
