Abstract Thermal barrier coatings (TBCs) can effectively protect the alloy substrate of hot components in aeroengines or land-based gas turbines by thermal insulation and corrosion/erosion resistance ceramic top coat. However, continuous pursuit a higher operating temperature leads to degradation, delamination, premature failure Both new materials coating structures must be developed meet demand for future advanced TBC systems. In this paper, latest progress some is first reviewed. Then,...
Abstract Proton exchange membrane water electrolyzer (PEMWE) technology is of interest in the context electrocatalytic hydrogen generation from renewable energies. It has benefits immediate response, higher proton conductivity, lower ohmic losses, and gas crossover rate. One key step toward to large‐scale application, development highly efficient, durable, compatible anodic oxygen evolution electrocatalysts acidic media decrease usage expensive scarce precious metals. Within this scenario,...
Surface reconstruction generates real active species in electrochemical conditions; rational regulating a targeted manner is the key for constructing highly catalyst. Herein, we use high-valence Mo modulated orthorhombic Pr3Ir1-xMoxO7 as model to activate lattice oxygen and cations, achieving directional accelerated surface produce self-terminated Ir‒Obri‒Mo (Obri represents bridge oxygen) that acidic water oxidation. The doped not only contributes due optimized Ir‒O covalency more prone...
Abstract Volcanic ash is a major threat to aviation safety. The softening/melting temperatures of volcanic lie far below typical aero‐engine operating temperatures. Thus, molten can accelerate the failure thermal barrier coatings (TBCs). Here, inspired by natural superhydrophobic surfaces (e.g., lotus leaf), molten‐volcanic‐ash‐phobic TBC, which provides large possibility eliminate issues TBCs, developed. A hierarchically structured surface first prepared on (Gd 0.9 Yb 0.1 ) 2 Zr O 7 (GYbZ)...
Abstract Aero-engine is a key part of aircraft, the operating temperature which being pushed to unprecedented levels for higher engine efficiency and performance. To accomplish gas-inlet aero-engines, applying thermal barrier coatings (TBCs) on hot-section metallic components, or even replacing some components in aero-engines with ceramic-matrix composites (CMCs) environmental-barrier (EBCs) them, are effective methods have been widely accepted. On other hand, increasing causes aircraft more...
Abstract Y 2 O 3 stabilized ZrO (YSZ) thermal barrier coatings (TBCs) are prone to hot corrosion by molten salts. In this study, the microstructure of atmospheric plasma spraying YSZ TBCs is modified laser glazing in order improve resistance. By optimizing parameters, a ∼18 µm smooth glazed layer with some vertical cracks was produced on coating surfaces. The as-sprayed and were both exposed tests at 700 1000 °C for 4 h V 5 salt, results revealed that one had improved After corrosion, kept...
Abstract Calcium-magnesium-alumina-silicate (CMAS) corrosion is an important cause for thermal barrier coating (TBC) failure, which has attracted increased attentions. In this study, some materials including YSZ (yttria partially stabilized zirconia), GdPO 4 , and LaPO were prepared into bulks, the effects of their surface roughness on wettability spreading characteristics molten CMAS investigated. As-fabricated polished bulks with different exposed to at 1250 °C 1 h, following by macro...
Abstract Sc was doped into Gd 2 Zr O 7 for expanding the potential thermal barrier coating (TBC) applications. The solid solution mechanism of in lattice, and mechanical thermophysical properties Gd2Zr2O7 were systematically studied by first-principles method, based on which doping content optimized. Additionally, Sc-doped TBCs with optimized composition prepared air plasma spraying using YSZ as a bottom ceramic (Gd-Sc/YSZ TBCs), their sintering behavior cycling performance examined. Results...
In aero-turbine engines, thermal barrier coatings (TBCs) must be capable to withstand harsh environments, such as high-temperature oxidation and hot-corrosion. Recently, a new failure mode of TBCs caused by calcium–magnesium–alumina–silicate (CMAS) glass has attracted increasing attention. this paper, yttria stabilized zirconia (YSZ) produced electron beam physical vapor deposition (EB-PVD) were exposed CMAS deposits at 1250 °C. The microstructure evolution mechanism the investigated. It...
