Abstract
Solar salt is currently used in concentrated solar power plants with thermal energy storage. Thermal decomposition of nitrates increases the concentration of oxidizing agents and melt basicity, leading to accelerated corrosion of containment materials. This is further complicated by the impurities in industrial-grade salts. In this study, the corrosion behavior of X20CrMoV12-1, Alloy 800 H, and Haynes-230 is investigated at 600°C in different solar salt mixtures with varying impurity contents. Corrosion mechanisms, including aspects of salt decomposition, impurities, and Cr-dissolution, are discussed in detail. It is proposed that the reactants for oxidation, fluxing, and nitridation are generated from either nitrate or nitrite anions at the alloy/scale interface.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
