Molten carbonates are among the ideal candidate materials for high-temperature thermal energy storage, but with high corrosiveness. In this study, a novel corrosion mitigation strategy, termed Air-then-Argon (AA) treatment, is proposed. This study investigates the corrosion behavior of three alloys (SS310, In625, and In601) in Li 2 CO 3 -K 2 CO 3 (28.5–71.5 wt%) carbonate melt under different gas conditions. The effect of the AA condition on the corrosion behavior of the immersed alloys was tested and compared with alloys directly immersed under argon (Ar) and air. Via weight loss method, it was shown that SS310 exhibited very low corrosion rates under both conditions, with slightly better performance under the Ar condition. In contrast, In625 showed much higher weight loss (146.6 ± 26.8 mg/cm 2 , for 200h) under argon compared to the AA condition. Under the AA condition, SS310 exhibited 84.8 % less weight loss than in air, while In625 had 90.1 % reduction compared to Ar atmosphere. For In601, the weight loss under Ar was the smallest among the samples tested. The microstructure and elemental distribution of the corrosion layers were analyzed with thermodynamic calculations of metal oxidation. The study summarizes the corrosion mechanisms of alloys in different gas environments and it reveals that the abnormal weight loss of In625 under inert conditions is mainly due to the oxidation and dissolution of Mo and Nb, which disrupted the protective LiCrO 2 layer. SS310 and In625 were tested under the AA condition in more challenging 700 °C carbonate melt. Weight loss data after 500 h confirmed effective corrosion mitigation. The corrosion bilayers formed on alloys exposed to carbonate melt in air exhibited excellent corrosion resistance when subsequently in argon, suggesting that controlling the gas environment could be an economical and effective method for mitigating carbonate corrosion.

LiCoO 2 has become the most widely used cathode material in lithium-ion batteries because of its high capacity and excellent stability. The high-temperature solid-state method is commonly used for the preparation of LiCoO 2 . However, this method will produce highly penetrating Li 2 O, which causes spall or fracture of the insulating refractory materials in the kiln. In this study, the corrosion resistance of bubble alumina, mullite, and calcium hexaaluminate (CA 6 ) insulating refractories to LiCoO 2 has been thoroughly investigated. Combining the laboratory-scale interfacial reaction experiments with post-experimental life cycle analysis of industrial insulating refractories, the interaction between the insulating refractory materials and LiCoO 2 after calcination at 900°C for 5 h and the corrosion behavior of LiCoO 2 on different insulating refractory materials following heat treatment at 900°C for 5 h every time and repeated seven times are investigated. The corrosion mechanisms are concluded by analyzing the physicochemical composition and macro- and micromorphology of the three insulating refractory materials before and after corrosion. The results can provide a basis for the use of insulating refractories in the development of lithium batteries.

Solar salts have a high energy storage density, and using solar thermal power generation technology can provide humanity with long-term, stable, and low-cost electricity. However, severe corrosion of structural materials when in contact with molten chloride salts is one of the main challenges limiting their long-term service at high temperatures. In this study, two types of aluminium-containing austenitic (AFA) stainless steels: 18Ni and 25Ni AFA steels, were prepared and their corrosion behavior in molten chloride salt (NaCl-MgCl₂-KCl with 30.2–47.1–22.7 mol.%) at 700 °C over different durations (200, 400, 600, and 800 h) was investigated. The corrosion products, thickness of the corrosion layer, and microstructure were characterized in detail. The effects of alloying elements on enhancing resistance to molten chloride salt corrosion were studied. Both types of AFA steels exhibited significant dissolution and oxidation behavior during the corrosion process, and the aggregation of Laves phases was observed. The corrosion depth after 800 h was found to reach a maximum of 131.3 μm, significantly lower than conventional 304 stainless steels under similar conditions. Why AFA steels exhibit resistance to chloride salt corrosion is discussed. The findings provide valuable guidance for the development of structural materials suitable for high-temperature molten chloride salt applications.

This work aims at revealing the key factors that limit the cleaner production level of a pickling process. By comparing the difference in their characteristics and the corrosion behaviors in an acidic medium, three kinds of sample, including the matrix steel (AS), the naturally-corroded carbon steel (NR) and the carbon steel treated under high temperature oxidation (OR), after immersed in the experimental solutions with or without hexamethylenetetramine (HA), were characterized with the methods, such as, electrochemical polarization, X-ray diffraction (XRD) and scanning electron microscopy (SEM). Results indicated, no matter which kind of rust layers , the adsorption of HA on their surface all accorded with the same adsorption isotherm . Although the rust layers did not change the adsorption pattern of HA directly, but their steric effect would influence the adsorption potential of HA; the forming process of rust layers (under different environmental conditions) heavily influenced their composition, structure, and the interface roughness between the rust layer and the metal matrix, and also influenced the corrosion behavior of samples in an acidic medium, which were the key factors that limited the cleaner production level of a pickling process. These results indicated that an object-oriented pickling strategy should be adopted for a practical pickling process.

The corrosion behavior of zinc-rich epoxy primers or paints (ZRPs) with different conducting polyaniline-grafted graphene (PANI/Gr) contents was investigated. Conductivity of the formed PANI/Gr nanosheets was significantly improved by employing the Gr as the inner template to synthesize the PANI. The protective properties and electrochemical behavior of coatings with artificial defects were investigated by monitoring the free corrosion potential versus time and by using localized electrochemical impedance spectroscopy (LEIS). A synergetic enhancement of the physical barrier role of the coating and the zinc sacrificial cathodic protection was achieved in the case of ZRP including PANI/Gr nanosheets. In addition, the ZRP mixed with the PANI/Gr at a content of 0.6% exhibited the best anticorrosion performance across the range of investigated PANI/Gr contents.Keywords:conducting polymer;PANI;LEIS;graphene;corrosion

A series of sodium iron titanate (NFTO)–fluorocarbon composite coatings have been prepared with the liquid-phase blending method. The effects of two types of NFTO, NFTO platelets, and NFTO whiskers, on the tribological and corrosion behaviors of the composite coatings, are systematically studied. The results show that the addition of NFTO can significantly enhance the friction-reducing and wear resistance performances of the fluorocarbon coating. Under dry sliding, the minimum specific wear rate is 1.67 × 10 −4 mm 3 /Nm for the platelet-filled composite coatings and 1.15 × 10 −4 mm 3 /Nm for the whisker-filled composite coatings, respectively, showing a decrease of 83.5 and 88.6% than that of pure coating. Under a simulated seawater environment, the minimum specific wear rate is 5.44 × 10 −5 mm 3 /Nm for the platelet-filled composite coatings and 0.84 × 10 −5 mm 3 /Nm for the whisker-filled composite coatings, respectively, showing a decrease of 90.5 and 98.5% than that of pure coating. The morphologies of worn surfaces, wear debris, and transfer films are analyzed, and the corresponding wear resistance mechanisms are discussed. The electrochemical impedance spectroscopy certifies a remarkably improved corrosion resistance of the composite coatings which have been immersed in 3.5 wt % NaCl solution for 30 days. The composite coating reinforced with 7.5 wt % platelets shows the highest resistance of 256.3 × 10 6 Ω·cm 2 , approximately two orders of magnitude higher than that of pure coating. © 2020 Wiley Periodicals, Inc.

Alloying is one of the effective approaches to boost the discharge property of magnesium (Mg) anodes for primary Mg-air batteries and recently micro-alloying is highly recommended at the aim of developing advanced primary Mg system. In this study, micro-alloyed extruded Mg0.5Zn0.2Ge (in wt.%) alloy is evaluated as an anode candidate for primary Mg-air batteries in both half-cell and Mg-air full cell configurations, in comparison with commercially accepted Mg anodes, typified by as-cast HP Mg and extruded AZ31 alloy. The corrosion behavior at open circuit potential (OCP) condition of the three materials is also compared through electrochemical tests. Mg0.5Zn0.2Ge alloy displays the most negative OCP value and the highest corrosion resistance at OCP. During discharge, Mg0.5Zn0.2Ge anode exhibits low wasteful-discharge rate and homogeneous dissolution that gives rise to the absence of “chunk effect”. Consequently, the anodic efficiency and specific capacity of Mg0.5Zn0.2Ge anode are superior to those of HP Mg and AZ31 anodes, e.g. 57.3% and 1257 mAh g −1 at 1 mA cm −2 . Additionally, Mg-air battery based on Mg0.5Zn0.2Ge anode offers higher cell voltage and specific energy than those assembled with HP Mg and AZ31 anodes, which can be further optimized by addition of electrolyte additives. Therefore, micro-alloyed Mg0.5Zn0.2Ge alloy can serve as a promising candidate for anode material of primary Mg-air batteries.

Compressor blades made of TC4 that are serviced in marine environments suffer from severe active corrosion under the synergetic effect of NaCl and H2O(g). A SiO2-Al2O3glass composite coating was applied on TC4 substrate for protection by first air spraying slurry and subsequent a suitable sintering process. The corrosion behavior of the SiO2-Al2O3glass composite coating and uncoated alloy in marine environment under the simultaneous effect of NaCl(s) and H2O(g) at 650 °C were investigated. The results indicated that the SiO2-Al2O3glass composite coating presented good corrosion behavior and provided protection for the alloy; the superior corrosion resistance is mainly attributed to the favorable effect of the SiO2-Al2O3glass composite coating on inhibiting self-sustainable oxychlorination. The detrimental effect of Ti on self-sustainable oxychlorination mechanism in marine environment are discussed.

β -type titanium (Ti) alloys have been extensively investigated as orthopedic implant materials due to their unique combination of low elastic modulus , high specific strength , corrosion resistance , and biocompatibility. In this study the mechanical properties , corrosion behavior, friction and wear performance, and cytotoxicity of β -type Ti–24Nb–38Zr–2Mo (TNZM) and Ti–24Nb–38Zr–2Mo–0.1Sc (TNZMS) have been comparatively investigated for orthopedic applications. Cold-rolling (CR) and cold-rolling plus solution-treatment (CR+ST) were performed on the as-cast (AC) alloys and their microstructures and material properties were characterized. The impact of Sc addition on the mechanical and corrosion properties, friction and wear behavior, and in vitro cytocompatibility of the TNZMS alloy was assessed. The CR+ST TNZMS alloy exhibited the best combination of properties among all the alloy samples, with a yield strength of 780 MPa, ultimate strength of 809 MPa, elongation of 19%, Young's modulus of 65.4 GPa, and hardness of 265 HV. Electrochemical testing in Hanks’ Solution indicated that the CR+ST TNZMS sample also showed the highest corrosion resistance with a corrosion potential of -0.234 V, corrosion current density of 0.07 µA/cm 2 , and corrosion rate of 1.2 µm/y. Friction and wear testing revealed that the TNZMS alloy showed higher wear resistance compared to the TNZM alloy and the wear resistance of the different samples was ranked CR > CR+ST > AC. Finally, both the CR+ST TNZM and TNZMS showed no-cytotoxicity towards MG-63 cells and the TNZMS exhibited slightly higher cytocompatibility than the TNZM alloy. Statement of significance This work reports the β -type Ti–24Nb–38Zr–2Mo (TNZM) and Ti–24Nb–38Zr–2Mo–0.1Sc (TNZMS) alloys fabricated by as-cast (AC), cold-rolling (CR), and cold-rolling plus solution-treatment (CR+ST) for potential orthopedic applications. The experimental results showed that the TNZMS alloy exhibited significantly enhanced mechanical, wear, and corrosion properties than those of TNZM alloy; and the CR+ST TNZMS possess a unique combination of the best mechanical and corrosion properties including a yield strength of 780 MPa, ultimate strength of 809 MPa, elongation of 19%, Young's modulus of 65.4 GPa, and corrosion rate of 1.2 µm/y in Hanks’ Solution.

Deep eutectic solvents (DESs) provide enormous opportunities for manufacturing functional, electronegative metal alloys with hierarchical structures—because of the broad working windows for electrochemical reactions and the advantages of multiscale directing chemistry. This work presents the electrodeposition preparation of a hierarchical-structured Cu–Zr amorphous alloy coating from ChCl–EG DES for the first time. The electrochemical behavior of Cu 2+ and Zr 4+ , and the comprehensive microscopic and structural characterizations of the obtained deposits, demonstrate a potential-dependent nucleation and growth mechanism of Cu and Zr species on the surface of Cu foil. The deposits yielded at the lower negative potentials containing small amounts of Zr (< 4.0 at.%) are two-phase, with fibrous Cu a Zr b O c compounds cross-growing on the surface of the leaf-like face-centered cubic Cu phase. In contrast, the deposit obtained at a higher negative potential presents a Christmas tree-like Cu–Zr amorphous alloy structure (9.03 at.% Zr), and the hierarchical multiscale ZrO 2 amorphous layer formed on its surface can enable the native alloy with better corrosion resistance.

The study investigated the corrosion behavior and mechanical performance of SiC/SiC composite joints with Y 2 O 3 -Al 2 O 3 -SiO 2 (YAS) interlayers under high-temperature steam environments at 1200 °C. Under low-flow conditions, partial disruption of Si-O and Al-O bonds in the YAS glass network reduced crosslinking, forming an aluminosilicate protective layer that inhibited further corrosion. Prolonged exposure led to Y 3+ migration and accumulation, resulting in Y 2 Si 2 O 7 precipitation and growth. High-flow conditions caused a thinner glass layer, continuous longitudinal cracks, and more severe erosion and dissolution of the YAS glass due to higher steam velocity. Despite these degradations, the joints exhibited satisfactory performance, maintaining shear strengths of about 40 ± 2 MPa after 15 h of low-flow exposure and about 36 ± 5 MPa after 5 h of high-flow exposure. These findings demonstrate that YAS interlayers provide excellent corrosion resistance and mechanical stability as a sealant for nuclear-grade SiC/SiC.

The promotion of ethanol gasoline aims to reduce exhaust pollutant emissions. However, this process faces challenges, including high corrosion rates and susceptibility to stratification. This study investigates the corrosion behavior of Q235 steel in ethanol-gasoline blends (EGBs) with varying concentrations of water and simulated corrosion solution (SL). The research employs electrochemical measurements, and surface analysis techniques (SEM-EDS, AFM, XPS) to evaluate the corrosion products and mechanisms. The results show that after soaking for 7 days in E50 containing a corrosive medium, the Q235 steel surface developed obvious corrosion pits, with greater corrosion observed in the SL-containing solution. The corrosion phenomena in both media are governed by charge transfer mechanisms, primarily controlled by the anodic reaction. Additionally, the adsorption energies of oxygen and sulfur atoms on the Fe (110) surface are −10.25 eV and −4.68 eV, respectively, and the oxidation corrosion products of iron are more stable than those of sulfides.
