Summary: The effect of 316 stainless steel on the corrosion of pressureless-sintered SiC in the vapor of molten NaCl-KCl-MgCl2 salt at 700 degrees C was studied. It was found that MgCl2•xH2O (x = 4, 6) hydrolyzed into HCl, which caused corrosion of the stainless steel. Some corrosion products dissolved and increased the concentration of elements Cr, Fe, and Ni in the salt, while others reacted with SiC to form Cr7C3, Fe3Si, and SiCl4. Reactions among SiC, stainless steel, and their corrosion products (FeCl2, CrCl2, and SiCl4) led to a corrosion depth of approximately 250 μm for 1000 hours.

Summary: The corrosion behavior and mechanism of 316SS alloy in NaCl-KCl-ZnCl2 molten salts were investigated. The annual corrosion rate initially increased and then decreased to a steady rate. No evident pitting and intergranular corrosion were observed. An oxide layer composed of various oxides formed on the surface of the 316SS samples. The corrosion mechanism involved the hygroscopicity of ZnCl2, the reactions with Fe and Cr, and the formation of nickel oxide. Removal of Zn(OH)2 or basic zinc chloride in NaCl-KCl-ZnCl2 is necessary for commercial application.

Summary: The study found that the oxide film formed on Type 316L stainless steel in molten FLiNaK salt is unstable and can only provide temporary corrosion protection. After the dissolution of the oxide film, selective dealloying of Cr and Fe from the steel leads to intergranular corrosion of Type 316L SS in molten fluoride salt.

Summary: The study investigated the effect of Te concentration in molten FLiNaK salt on the corrosion and mechanical properties of 304 stainless steel. The corrosion depth of samples decreased with increasing Te concentration after 48 h immersion at 600 degrees Celsius. Additionally, the 1.0 wt% Te sample showed less reduction in mechanical properties compared to the 0.1 wt% Te sample. It is hypothesized that a protective Cr-oxide layer is formed beneath the Ni-Fe rich layer formed by selective leaching of Cr.

Summary: The effects of boric acid and lithium hydroxide on the corrosion behaviors of 316LN stainless steel in simulated high-temperature pressurized water were investigated. The results showed that increasing the concentration of boric acid or lithium hydroxide decreased the corrosion resistance of 316LN stainless steel. Boric acid was recommended for the water chemistry, while lithium hydroxide alone was found to be inappropriate. The solubility of oxides in high-temperature pressurized water was calculated, and a promising water chemistry for high-temperature pressurized water was proposed.

Summary: EH40 steel's corrosion behavior in seawater enriched with Methanococcus maripaludis was investigated, showing initial inhibition of corrosion followed by eventual propagation. The presence of M. maripaludis promotes both anodic and cathodic reactions of EH40 steel, while the protective corrosion products film inhibits corrosion during early immersion stages. Pitting corrosion is closely related to uneven distribution of M. maripaludis biofilm on EH40 steel surface.

Summary: This study investigates the corrosion behavior of GH3535 alloy in molten LiF-BeF2 salt. The results indicate that the corrosion is driven by NiF2 in the salt and O-2 leakage. The corrosion is severer in the hot section compared to the cold section. BeCr2O4 is detected on the alloy surface in the cold section but not in the hot section. Reactions between Be and metallic fluorides significantly reduce the impurity concentration in the molten salt, resulting in no obvious corrosion in the GH3535 alloy at different temperatures.

Summary: The increased demand for renewable energy resources has sparked a renewed interest in nuclear reactors, including a new generation of molten salt reactors. The handling of molten chloride or fluoride salts poses a challenge due to the inability of metals to form and retain a protective oxide surface layer. A specific alloy, Hastelloy N, was developed to address this issue, but it had some deficiencies. For the next generation of molten salt reactors, an alloy with higher temperature capability and pressure vessel code approval is required, leading some reactor designers to opt for 316H stainless steel. To minimize corrosion of the stainless steel by the molten fluoride salt, beryllium metal can be added to react with impurities and lower the oxidation potential. However, there are concerns about the potential reaction between beryllium and the stainless steel components.

Summary: The effects of Zn injection into boric acid and lithium hydroxide solutions on the corrosion behaviors of 316LN stainless steel in simulated high-temperature pressurized water were examined. It was recommended to use low concentration of lithium hydroxide solutions with 20-100 ppb Zn injection for Zn-injected water chemistry in high-temperature pressurized water environment. The study confirmed the beneficial effects of Zn injection in terms of protecting the oxide films on 316LN stainless steel, both in the hot functional test and primary coolant water chemistry. The corrosion mechanism during the Zn injection in high-temperature pressurized water was also discussed.

Summary: In this study, chemical vapor deposited SiC single crystal and polycrystals were exposed to a static beryllium-bearing molten fluoride salt, 2LiF-BeF2, at 750°C for 500 and 1000 hours. The materials experienced slight weight loss and surface etching, which were attributed to trace metal impurities and oxygen. Minimal subsurface changes were observed in the microstructure. The corrosion processes were similar to those reported for molten LiF-KF-NaF salt with trace impurities, indicating the significant impact of impurities on SiC corrosion.

Summary: Desalinated sea sand concrete (DSSC) is increasingly used to replace natural river sand, but the corrosion risks of steel reinforcement in DSSC due to chloride and carbon dioxide attacks are a major concern. This study monitored the corrosion process of steel reinforcement embedded in cement paste containing chloride ions and found that corrosion was initiated before carbonation occurred. The study reveals that carbonation-induced chloride redistribution rather than pH decrease dominates the corrosion initiation.

Summary: The experiment investigated the corrosion behavior of 316 stainless steel in NaCl-KCl-MgCl2 salt vapor at 700 degrees C under static conditions. Easy-to-peel oxide layers were formed on the surface, with their composition and structure changing as exposure continued. The initially formed oxide monolayer gradually transformed into oxide multilayers, with the outermost layer changing from Cr-Fe oxide to Mg-Cr oxide, due to varying diffusion rates of elements and different reaction rates of MgCl2 in the salt vapor.

Summary: This study aims to build a thermodynamic database for the LiCl/RbCl/CaCl2-NaCl-UCl3-PuCl3 system and evaluate the suitability of LiCl, RbCl, and CaCl2 as additives for the matrix fuel of a Molten Salt Reactor. The CALPHAD method is used, and models including substitutional solution and compound energy formalism are adopted to describe the phases. The models are optimized based on experimental and theoretical data, and the thermodynamic parameters are obtained. Phase diagram information is predicted, and the impact of LiCl, RbCl, and CaCl2 on the matrix fuel is investigated. The results suggest that RbCl is a suitable additive, while LiCl and CaCl2 are not. This study enriches the thermodynamic databases and provides guidance for the design and preparation of nuclear fuel in a Molten Salt Reactor.

Summary: Corrosion tests were conducted on 316 stainless steel (316SS) in NaCl-KCl-NaF reciprocal salts at different temperatures. The results showed perfect compatibility between the reciprocal salts and 316SS, even without special treatment, and a stable Cr-O enriched layer was observed. The mechanism of stabilization of chromium oxides in molten salts was investigated, revealing that low oxoacidity facilitated the formation of stable chromium oxides. These findings can potentially contribute to the design and corrosion control of molten salts.

Summary: The corrosion resistance of 316 stainless steel (316SS) in molten KCl-MgCl2 salts at high temperatures was investigated. The corrosion rate of 316SS increased slowly with temperature below 600 degrees C, but increased dramatically at 700 degrees C. The corrosion of 316SS was mainly due to the selective dissolution of Cr and Fe at high temperatures. Impurities in the salts accelerated the dissolution process, while purification treatment reduced the corrosivity of the salts. The diffusion rate of Cr/Fe in 316SS changed more with temperature than the reaction rate of salt impurities with Cr/Fe under the experimental conditions.

Summary: The corrosion behaviors of 316 stainless steel in NaNO3-NaCl-NaF molten salt and vapor were investigated at 450°C. The results showed that weight gain occurred in argon gas condition while weight loss occurred in air condition. Fe-O enriched layer with different crystal forms was detected by XRD. The crystal forms were relatively homogeneously distributed after molten salt corrosion but not uniform after vapor corrosion. 316 stainless steel experienced a more serious corrosion attack in salts vapor than in molten salt.

Summary: High porosity Co-Al-Fe intermetallics with 3D-microstructures were successfully synthesized in one step via a thermal explosion reaction. The link between pore structure and permeability was investigated using 3D-XRM technology. The corrosion resistance of the samples with different Fe contents was studied at 900 degrees C under an oxygen/sulphur atmosphere for up to 120 h. The results showed that the samples maintained stable pore structure and intact internal matrices, attributed to the formation of a thin protective layer on the surface. In addition, inward diffusion of S resulted in the formation of FeS nodules.

Summary: In this study, an environmentally friendly volatile corrosion inhibitor, lysine salts (LA), was prepared between graphene oxide (GO) layers using an in situ intercalation technique. The corrosion inhibition effect of LA was evaluated, and it was found that LA-GO2 achieved a 99.3% corrosion inhibition efficiency after composition optimization. The inhibition of the electrochemical anodic process on the surface of mild steel was the main reason for the high corrosion inhibition efficiency of LA-GO2. The properties of the surface film on the corroded steel were also characterized in detail to understand the corrosion inhibition mechanism of LA-GO2.

The electrochemical activity under the coating was evaluated by mapping the ionic current densities coming from artificial defects made in specific locations of the filament. Antimony tips were also used to investigate the pH changes associated with different corrosion reactions at the metal-paint interface. Local pH levels along the filament in the anodic and cathodic regions were determined.
