“…It was shown that the external scale was made of iron–chromium spinel, (FeCr 2 O 4 ) and sodium ferrite, (NaFeO 2 ). [ 15–18 ] As established above, the presence of Cr on the external scale was minimum, and in some research studies, it was found that an increase in the Cr contents and in the immersion time accelerates the dissolution of this element. [ 14 ] Similarly, the presence of Na and very little Cr is evident at the outer scales formed on the corrosion products of the different high‐Ni, high‐Cr alloys, as shown in Figures 10–12, indicating that this layer can be formed by the inward diffusion of Na and outward Cr dissolution.…”

The corrosion behavior of three high-Ni, high-Cr alloys, that is, UCX, KHR35, and KHR45 alloys, in a mixture of 60% NaNO 3-40% KNO 3 at 600°C has been evaluated by using weight loss tests, potentiodynamic polarization curves, and electrochemical impedance spectroscopy measurements. Cr contents ranged between 23.25 and 43.2 wt.%, whereas Ni ranged between 36.6 and 50.3 wt.%. For comparison, the same studies were performed on 304-type stainless steel (304SS). Tests were complemented with detailed scanning electronic microscope and X-ray diffraction studies. Results showed that that the three high-Ni, high-Cr alloys had lower weight loss than that for 304SS. Polarization tests indicated the formation of a passive layer in all cases. Electrochemical impedance spectroscopy data have shown that the corrosion mechanism for all the alloys was charge transfer from the alloy to the molten salt. Finally, X-ray patterns showed the presence of Cr 2 O 3 in all tested alloys, which is responsible for the observed passive behavior and their corrosion resistance.

Bibliometric Map on Corrosion in Concentrating Solar Power Plants

2022

Concentrating solar power (CSP), also known as solar thermal electricity (STE), is increasing its deployment worldwide. One of the potential ways to decrease costs in CSP plants is the improvement of corrosion resistance between the heat transfer fluid (HTF) and storage materials, and the materials used for pipes, tanks, containers, and receivers. This paper assesses the literature on this topic (290 publications) through a bibliometric analysis, identifying the trends of the research, the topics of most interest to researchers, and literature gaps. Most documents are from Spain, Germany, and the United States of America. Results show that the most recent approaches for corrosion migration are selective coatings and the use of nanoparticles to reduce corrosiveness. The use of nitrates is changing to other salts such as chloride mixtures and potassium compounds. In addition, the techniques used to evaluate corrosion results are dominated by scanning electron microscopy (SEM), X-ray diffraction (XRD), and electrochemical testing, but new dynamic techniques are starting to be used, representing the biggest gap that needs to be filled for the testing of components such as solar receivers.
