To investigate the influence of Mo addition and water vapor content on the high-temperature corrosion resistance of Ni-Al-based coatings, 0Mo, 5Mo, and 10Mo coatings were deposited by APS thermal spray onto stainless steels. The chlorine-induced corrosion test was conducted in an experimental environment simulating a biomass boiler. The results show that adding the Mo element lowers the coating's ability to resist corrosion without water vapor. The coating is more prone to peeling because Mo prevents the coating from eventually forming a protective oxide layer. Water vapor significantly speeds up the production of oxides and modifies their morphology and structure. The combined effects of Mo and water vapor increase the coating's ability to resist corrosion. The development of thick and protective Ni and Al oxide layers on the coated surface is aided by the acceleration of oxide production by water vapor and the alteration of oxide structure by Mo components.

The high-temperature corrosion behavior of a Si 3 N 4 /W composite under the molten MgCl 2 -NaCl-KCl salts has been investigated. It is suggested that the molten salts diffuse along the physical surface defects and enter the interior of adjacent Si 3 N 4 /W grains, leading to the 9.1% bending strength loss after 400 hours for corrosion. In air atmosphere, oxidation products WO 2 , WO 3 , and corrosion product MgWO 4 caused a 34.3% bending strength decrease after 400 hours for corrosion. This study elucidates the high-temperature molten chloride salt corrosion mechanisms of the Si 3 N 4 /W composite material under two different atmospheres. The composite demonstrates relatively excellent corrosion resistance in service environments.

The study examined the impact of varying molybdenum content (0 %, 5 %, and 10 % wt) on the high-temperature corrosion resistance of APS-sprayed Ni-clad Al coatings. The coatings were exposed to a simulated biomass-firing environment with pure KCl deposition at 600 °C for 168 h, and a mixed gas containing 15 % water vapor was passed through. The findings revealed that increasing Mo content improved the coating's high-temperature corrosion resistance. The coating with 10 % Mo displayed a continuous layer of Ni and Al oxides on its surface, while KCl was concentrated in the Mo region. Based on the experimental results, a mechanism for how the presence of Mo element contributes to the high-temperature corrosion resistance of NiAl coatings was proposed.

The effect of Sc 2 O 3 content on the corrosion behaviors of x Sc 2 O 3 -3.5Y 2 O 3 co-doped ZrO 2 (ScYSZ, x = 4.5, 5.5 and 6.5 mol.%) in calcium-magnesium-alumino-silicate (CMAS) at 1300 °C was investigated in this paper. It is shown that the ScYSZ ceramic exhibits better resistance to molten CMAS attack when doping with more Sc 2 O 3 . The CMAS penetration depth in the ScYSZ ceramic decreases with increasing Sc 2 O 3 . It is about 18 µm of CMAS penetrated depth in the 6.5Sc3.5YSZ after corrosion for 4 h at 1300 °C, including an 11 µm and 7 µm for the reaction-reprecipitation and grain-boundary infiltration layers, respectively. High thermochemical stability and weak reactivity of the ScYSZ to the glassy CMAS melt are beneficial to enhance the high temperature corrosion resistance, attributing to the low solubility in molten CMAS and the weak affinity to Ca 2+ for small ionic radius Sc 3+ . The mechanism of enhancing the resistance to CMAS is discussed.

In the fields of nuclear engineering and solar thermal utilization, low melting point alloys with excellent thermal conductivity and heat transfer performance have attracted extensive research as a new generation of heat transfer fluids, leading to many fundamental and important application issues. This study investigates the high-temperature corrosion behavior of Sn-50Bi-2Zn (wt.%) heat transfer alloy against 304 stainless steel (304), 310S heat-resistant steel (310S), and 20 carbon steel (20C) at 600 °C. Theoretical analysis, based on Fick’s diffusion law, and experimental measurements reveal significant differences in corrosion severity. After 473 h, 20 carbon steel exhibited the lowest corrosion layer thickness (0.07 mm), while 310S suffered the most severe corrosion (1.50 mm), exceeding 304SS (0.83 mm) by 81%. Diffusion coefficients derived from Sn penetration depths further quantified these trends: D310S = 2.51 × 10−7mm2/s (6.8 × higher than 304: 3.7 × 10−8mm2/s) and D20C = 2.87 × 10−10mm2/s (128 × lower than 304SS). XRF analysis confirmed the dissolution of steel components into the molten alloy, with Fe, Cr, and Ni content increasing to 0.382 wt.%, 0.417 wt.%, and 0.694 wt.%, respectively, after 480 h. These results underscore the critical role of Ni content in accelerating Sn/Zn diffusion and pore formation, providing actionable insights for material selection in high-temperature heat transfer systems.

Calcium–magnesium–alumina–silicate (CMAS), as an environmental deposit, deposits on engine components and causes serious damage to traditional thermal barrier coatings (TBCs) at high temperatures. The rare-earth silicate apatite dense reaction layer is regarded as a promising strategy to prevent TBCs from molten CMAS penetration and corrosion. The interactions between the Gd2O3ceramic and CMAS are discussed at various temperatures and times in the study. The main reaction products are gadolinium silicate apatite (Ca2Gd8(SiO4)6O2, Gd-apatite) and melilite phases. Within the first 15 min of interaction, a thin, continuous and dense reaction layer (DRL) consisting of Gd-apatite comes to form, and it thickens with increasing exposure temperature and time. The thickness of the DRL is ~0.8 μm after 15 min of the reaction at 1250 °C and it slowly increases to ~9.1 μm after a duration of 24 h at 1400 °C. This is attributed to CMAS infiltration along the grain boundaries of the Gd-apatite phases in the DRL. The growing rates of the Gd-apatite DRL decrease with reaction time and are significantly influenced by the temperature and the ability of the DRL to inhibit CMAS infiltration.

The thermochemical reaction behaviors between Y 2 O 3 and calcium-magnesium-aluminosilicate (CMAS) at 1250 °C∼1400 °C were investigated. A continuous-dense reaction layer mainly composed of Y-apatite phase quickly forms within 15 min, and its slow increasing thickness depends on the molten CMAS infiltration along the Y-apatite grain boundaries, the dissolution of the Y-apatite phase into the melt, the inhibiting effect on the CMAS penetration, and the reaction time and temperature. The CMAS crystallization occurs due to the change of chemical composition and the formation of other reaction products. The dense reaction layer shows good resistance to the molten CMAS infiltration.

The high-temperature corrosion behavior of an AlN/Mo functionally graded material (FGM) under the Li/LiF-LiCl-LiBr vapor has been investigated. It is suggested that the Li vapor diffuses along the AlN and AlN/Mo grain boundaries and enters the interior of adjacent AlN grains, leading to the disintegration of AlN grains and subsequent failures. The 3D Mo networks are barely corroded, thus preventing cracking that may occur due to the inconsistent deformation inside the FGM. This work unravels the high-temperature corrosion mechanisms for the AlN/Mo FGM. Meanwhile, the operating temperature threshold for the liquid metal batteries employing Mo/AlN/Mo seals is determined to be ∼ 600 °C.

The high temperature corrosion inhibition mechanism of sodium dodecyl diphenyl ether disulfonate (MADS) on ADC12 aluminum alloy in oxalic acid solution at 80 °C was investigated using electrochemical measurements, surface characterization and theoretical computations. The results manifested that MADS still had excellent performance in high-temperature oxalic acid solution, and was a highly efficient and long-lasting corrosion inhibitor with an optimal corrosion inhibition efficiency ( ƞ ) of 90.90 %. With increasing soaking time, the ƞ increased to 98.70 %. MADS molecule adsorbed on the aluminum alloy surface in an L -shaped walking scooter configuration through physicochemical adsorption to form a dense, thin and stable hydrophobic film, inhibiting the formation of aluminum oxalate and Al 2 O 3 , and protecting it from corrosion.

Environmental silicate deposits are among the most critical factors driving high-temperature degradation of thermal barrier ceramics, yet the intrinsic corrosion mechanisms remain insufficiently understood. Rare-earth zirconates (RE 2 Zr 2 O 7 ) have emerged as promising next-generation candidates, but their resistance to molten silicate attack varies widely with the choice of rare earths. Here, we systematically investigate 15 RE 2 Zr 2 O 7 compositions based on La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Y, Er, Tm, Yb, Lu, and Sc. High-temperature wetting and long-term corrosion experiments at 1300 °C reveal a multivariate dependence of molten silicate spreading and degradation on RE ionic radius, which we examine in terms of lattice energy, RE–O bond ionicity, optical basicity, apatite formation enthalpy, and RE content in fluorite products. Two distinct corrosion modes can be identified: exemplified by exhibits dissolution-controlled interfaces lacking protective barriers (e.g., Tm zirconates) and precipitation-controlled interfaces composed of either dense RE/Ca-apatite/fluorite (e.g., La zirconates) or Sc-garnet layers (Sc zirconates) that act as protective barriers. These results elucidate the fundamental role of rare-earth chemistry in CMAS reactivity and provide mechanistic guidance for designing compositionally optimized (high-entropy) zirconates with superior environmental durability for advanced aero-engine and gas turbine applications.

Thermal shock and hot corrosion resistance of SiC whisker enhanced polycarbosilane-derived ceramic coatings on TC4 substrate were studied. The mass loss of coating enhanced by SiC whiskers was 0.125 mg·cm⁻² after 200 thermal shock cycles from 600 °C to room temperature, which was reduced by 82.8 % compared with that of without SiC whiskers. The magnitude of mass fluctuation during hot corrosion at 600 °C for 200 h is significantly lower for coatings with SiC whiskers than without SiC whiskers. SiC whiskers not only prevent the formation and propagation of penetrating cracks, but also increase the viscosity of molten glass fillers which can repair the formed cracks and pores, thereby enhancing the thermal shock and hot corrosion resistance.

Thermal and environmental barrier coatings (TEBCs), an up-to-date concept, are introduced to protect silicon-based ceramic matrix composites (CMCs) from not only high-temperature water vapor but also alkali salts from volcanic ash and dust suspended in the atmosphere. Both high-temperature steam and CMAS will cause Si-based CMCs to deteriorate rapidly. By executing the corrosion test against high-temperature water vapor, we find that the Y 2 SiO 5 /Si double-layer TEBC can effectively protect SiC f /SiC CMCs from water vapor at 1300 °C for over 205 h. Almost all Y 2 SiO 5 transforms into Y 4.67 (SiO 4 ) 3 O after the corrosion test. It is also found that in the CMAS corrosion test, the reaction zone formed between the CMAS and Y 2 SiO 5 layers prevents the mutual diffusion of elements in the CMAS and Y 2 SiO 5 layers. The apparent activation energy of the reaction between CMAS and Y 2 SiO 5 in the 1200–1300 °C temperature range is calculated to be 713.749 kJ/mol. These findings provide a reference for selecting appropriate materials for TEBCs.
