Crevice corrosion of solution annealed 25Cr duplex stainless steels: Effect of W on critical temperatures

Cristian Torres et al.

Summary: The study demonstrates that the addition of tungsten can enhance the crevice corrosion resistance of super duplex stainless steels, leading to higher initiation and repassivation crevice temperatures.

Oxidation and hot corrosion resistance of HVOF/EB-PVD thermal barrier coating system

Kadir Mert Doleker et al.

Summary: In this study, different coating techniques were used to prepare coatings, which were then subjected to tests under various conditions. The results showed that the Gd2Zr2O7 layer exhibited superior thermal oxidation and corrosion resistance compared to the conventional YSZ TBC system.

Comparison of calcium-magnesium-alumina-silicate (CMAS) resistance behavior of produced with electron beam physical vapor deposition (EB-PVD) method YSZ and Gd2Zr2O7/YSZ thermal barrier coatings systems

Yasin Ozgurluk et al.

Summary: Metal powders were cold gas dynamic sprayed on Inconel 718 nickel-based superalloy substrate materials to form thermal barrier coatings. Single and double layer ceramic layers were deposited using physical vapor deposition by electron beam. It was found that the double layer TBC system with GZO/YSZ is more resistant to CMAS damage compared to the single layer YSZ system.

Investigation of calcium-magnesium-alumino-silicate (CMAS) resistance and hot corrosion behavior of YSZ and La2Zr2O7/YSZ thermal barrier coatings (TBCs) produced with CGDS method

Yasin Ozgurluk et al.

Summary: The study investigated the impact of high-temperature oxidation, hot corrosion, and CMAS attacks on YSZ and La2Zr2O7/YSZ TBC systems, revealing that double-layered TBCs provide better durability than traditional YSZ TBCs. Hot corrosion and CMAS attacks significantly damaged the column morphology of the EB-PVD method, reducing the performance of thermal barrier coatings.

TGO growth and kinetic study of single and double layered TBC systems

Kadir Mert Doleker et al.

Summary: Thermal barrier coating (TBC) systems are widely used to extend the lifetime of hot section components in gas turbines, but oxidation degradation at high temperature is still inevitable. In this study, YSZ/CoNiCrAlY/Inconel 718 and LZO/YSZ/CoNiCrAlY/Inconel 718 TBC systems were exposed to high temperature oxidation tests, with the double-layered LZO/YSZ TBC system showing better performance but leading to crack formation. Higher temperatures and longer oxidation periods can degrade the integrity of top coatings due to the sintering effect. Chemical incompatibility did not affect the interface durability of the LZO/YSZ TBC system during the oxidation tests.
