Summary: This study investigates the effect of nanoparticles in molten salt-based nanofluids on the corrosion behavior of different alloys. The results show that nanoparticles generally increase the corrosion rate of the alloys to varying extents. However, the impact of nanoparticles on corrosion rate depends on the specific alloy and nanoparticle concentration.

Summary: This review summarizes past research on heat transfer fluids (HTF) containing material used in concentrated solar power (CSP) plants, with a focus on chloride molten salts. The low cost and wide operating temperature range of these salts make them potential candidates for future CSP plants, especially if nanoparticles are added to enhance their performance. However, their aggressive behavior requires the selection of long-lasting resistant alloys, and a better understanding of corrosion mechanisms and the effects of alloying elements. The article also discusses strategies for mitigating salt impurities through purification processes, and presents thermogravimetric analysis and numerical simulations for salt preparation and modeling alloy activities and their interaction with molten chlorides.

Summary: The corrosion layers of GH3535 and Inconel 625 alloys in the 40 KNO3-60 NaNO3 (wt%) at 500 degrees C for 500 h were characterized using advanced electron microscopy. The results indicate that the corrosion depth of Inconel 625 alloy is smaller than that of GH3535 alloy. The corrosion products differ for the two alloys, which can be attributed to the higher content of molybdenum in GH3535 and chromium in Inconel 625 alloy.

Summary: The technical limit of solar towers today is represented by the temperature that current accumulation and exchange fluids can reach, with molten salts generally adopted and maximum temperatures below 600 degrees C. An ongoing experimental project named Nextower proposes an innovative solution based on liquid lead to accumulate heat at higher temperatures by transferring experience from the field of nuclear plants.

Summary: This paper investigates the effect of applying and directing a constant magnetic field on the electrodeposition and magnetic properties of refractory metal alloys (W, Mo, Re) with cobalt from citrate-pyrophosphate electrolytes. The study finds that the magnetic field has the greatest influence on the electrodeposition of rhenium alloys, resulting in a decrease in rhenium content and halving of crystallite sizes.

Summary: Potassium nitrate and sodium nitrate mixture, known as solar salt, has been used as a heat storage medium for concentrated solar power plants for over a decade. However, corrosion of metallic components in contact with solar salt at high temperatures can be an issue. This study conducted dynamic corrosion tests on 19 different material types to simulate in-service conditions and compared the results to static corrosion tests reported in literature.

Summary: This study investigates the effect of Cl- on the stability of a nickel anode in molten salt system and finds that the nickel anode experiences severe corrosion when the Cl- concentration exceeds a critical value. Additionally, the study also discovers that the addition of CaCO3 can effectively protect the anode from Cl- induced corrosion.

Summary: This study systematically investigated the stable dissolved valence state of iron fluorides in molten FLiNaK salt and their effect on GH3535 alloy. The destabilization of Fe (II) in the molten salt and its conversion to more stable Fe (III) through a disproportionation reaction were found to aggravate the corrosion of the alloy due to a redox reaction.

Summary: This study aimed to develop a single layer ZrB2-SiC-based ceramic absorber coating on stainless steel substrate and investigate the degradation of ZrB2-SiC ceramic in molten solar salt. The corrosion rate in solar salt was found to be 0.73 +/- 0.09 mg h(-1)/cm(2). The hot-pressed ZrB2-SiC ceramic exhibited high solar absorptance and thermal emissivity, making it suitable for concentrated solar power applications.
