Hot corrosion and CMAS degradation of laser-glazed YSZ coating with optimum parameter

Ali Avci et al.

Summary: The purpose of this research is to investigate the effects of laser surface modification on the resistance to hot corrosion and hot corrosion with calcium-magnesium aluminosilicate (CMAS) of YSZ thermal barrier coatings. A bond coat of Metco AMDRY 997 (Ni-22Cr-10Al-Y) powder was applied using a high-velocity oxy-fuel spray technique, followed by plasma spraying of 204 NS YSZ (ZrO2•8Y2O3) particles as the ceramic top layer. The entire coating surface was then treated with a 20-kHz pulsed CO2 laser. The laser-modified coatings exhibited denser surfaces, improved hot corrosion resistance, and reduced corrosion products compared to unmodified coatings.

Hot-Corrosion Behavior of Gd2O3-Yb2O3 Co-Doped YSZ Thermal Barrier Coatings in the Presence of V2O5 Molten Salt

Yang Li et al.

Summary: In this study, thermal barrier coatings (TBC) consisting of 3.5 mol% Yb2O3-stabilized ZrO2 co-doped with 1 mol% Gd2O3 and 1 mol% Yb2O3 were fabricated. The GdYb-YSZ TBCs showed improved corrosion resistance to V2O5 molten salt compared to YSZ TBCs. The corrosion products formed on the GdYb-YSZ TBCs included Yb, Gd-doped YVO4, and m-ZrO2.

CMAS Corrosion Resistance Behavior and Mechanism of Hf6Ta2O17 Ceramic as Potential Material for Thermal Barrier Coatings

Sai Liu et al.

Summary: Thermal barrier coatings (TBCs) face a serious threat from calcium-magnesium-alumina-silicate (CMAS) corrosion. The search for new ceramic coatings with excellent resistance to CMAS corrosion for TBCs is ongoing. This study investigates the CMAS corrosion resistance behavior and mechanism of a promising Hf6Ta2O17 ceramic coating. Results show that temperature is the most important factor affecting CMAS behavior and mechanism, with different corrosion products formed at different temperatures.

Degradation and failure of a novel double-layer LC/YSZ thermal barrier coating in a burner rig corrosion test

Y. X. Kang et al.

Summary: Thermal barrier coatings (TBCs) are vulnerable to corrosion by molten calcium-magnesium-aluminium-silicate (CMAS) during high temperature service. This study comparatively investigated the microstructural evolution and thermal cycling lives of double-layer La2Ce2O7 (LC)/yttria partially stabilised zirconia (YSZ) and single-layer YSZ coatings through a burner rig corrosion test. The results demonstrate that the thermal cycling life of double-layer LC/YSZ coating is approximately 80% longer than that of single-layer YSZ counterpart. CMAS penetration into the entire YSZ coating significantly accelerated the spallation failure, whereas the sintering of the LC layer, owing to its superior CMAS resistance, primarily caused the failure of the double-layer LC/YSZ coating, resulting in large in-plane stress and crack initiation.

Comparative study on microstructure evolution and failure mechanisms of ordinary and refurbished EB-PVD TBC under cyclic oxidation

Pan Li et al.

Summary: The refurbishment process can significantly affect the microstructure and physical properties of thermal barrier coatings (TBC). In this study, the influence of the refurbishment process on oxidation characteristics, element diffusion behavior, and crack failure mechanisms of TBC was investigated. The results revealed that the microstructure and growth mechanism of oxide layers in refurbished TBC specimens were different from ordinary TBC specimens.

Effect of Morphology, Impact Velocity and Angle of the CaO-MgO-Al2O3-SiO2 (CMAS) Particle on the Erosion Behavior of Thermal Barrier Coatings (TBCs): A Finite Element Simulation Study

Yao Liu et al.

Summary: This study proposes a simplified model to simulate the erosion of YSZ TBCs by high-speed CMAS particles and investigates the physical damage behaviors of the TBCs under various contact configurations, impact velocities, and impact angles. The findings suggest that the contact configuration significantly affects the residual stress and microcrack formation of the coating, while the erosion velocity and angle contribute to the delamination failure.

Interfacial Stresses of Thermal Barrier Coating with Film Cooling Holes Induced by CMAS Infiltration

Chenchun Chiu et al.

Summary: Film cooling holes and CMAS infiltration have significant effects on temperature and residual stress in thermal barrier coatings. Film cooling holes can alleviate interfacial residual stress, while CMAS infiltration intensifies it. The increase in residual stress is mainly due to the larger penetration depths and expansion rates of phase transformation.

Preparation and CMAS Wettability Investigation of CMAS Corrosion Resistant Protective Layer with Micro-Nano Double Scale Structure

Yihao Wang et al.

Summary: Solution precursor plasma spray (SPPS) can prepare thermal barrier coatings (TBCs) with nanostructures, improving their resistance to corrosion. The micro-nano double scale structures formed by SPPS can trap air and form an air layer between the coating surface and the molten CMAS. Nano-particles play an important role in forming the air layer, while micron structures impact the time needed to reach the steady-state.

Corrosion resistance of modified YSZ coatings subjected to CMAS attacks

Zhe Wang et al.

Summary: The deterioration of thermal barrier coatings in reaction engines due to CMAS attacks has been an important issue recently. The addition of AT powder into YSZ and the use of APS to fabricate coatings are effective methods to enhance the corrosion resistance against CMAS. The AT-YSZ coating shows better adhesion and fewer defects compared to YSZ coating after CMAS attack, and different phases are formed.

Summary: The study investigated the effects of partial Y2O3 substitution by Gd2O3 on the thermal and mechanical properties of ZrO2-Ta2O5-Y2O3 ceramics. Results showed that Gd2O3 substitution decreased phase stability and thermal conductivity, but increased thermal expansion coefficients of the materials.

Hot corrosion behavior of ZrO29.5Y2O35.6Yb2O35.2Gd2O3TBCs in CMAS: CaO-MgO-Al2O3-SiO2

M. Bahamirian et al.

Summary: This study aims to improve the hot corrosion resistance of thermal barrier coatings in aero-engines in CMAS environments, by introducing a new coating ZGYbY to enhance the quality and efficiency of 8YSZ. The results indicate that the ZGYbY coating performs better in preventing CMAS diffusion compared to 8YSZ, potentially due to the formation of impermeable apatite compounds.

Calcium-Magnesium-Aluminum-Silicate (CMAS) Corrosion Resistance of Y-Yb-Gd-Stabilized Zirconia Thermal Barrier Coatings

Tongxin Wang et al.

Summary: This study investigated the role of Y, Gd, and Yb in resisting CMAS corrosion in zirconia-based TBCs. The results showed that, compared to YSZ coatings, CMAS penetrated deeper in YSZ-Yb-Gd coatings after the same corrosion time. The addition of small amounts of Yb and Gd did not improve the CMAS resistance of YSZ TBCs.

Al2O3-TiO2 Codoped Yttria-Stabilized Zirconia Thermal Barrier Coatings Resistant to Damage by Molten Calcium-Magnesium-Alumino-Silicate (CMAS) Glass

Ke Yuan et al.

Summary: This study investigates the CMAS resistance of Al2O3-TiO2 co-doped yttria-stabilized zirconia (YSZ), and finds that YSZ doped with 10 mol% Al2O3 and 5 mol% TiO2 (10A5TYSZ) shows better resistance to CMAS corrosion and suitable thermal conductivity. The formation of anorthite in 10A5TYSZ coating helps increase the melting point of CMAS and block its penetration, effectively preventing further CMAS infiltration and premature failure of TBCs.
