In situ ICP-MS analysis of passivation process and selective dissolution of Fe-15Cr alloy in sulfuric acid
The dissolution of Fe-15Cr alloy during potentiodynamic polarization in sulfuric acid was quantified in situ using inductively coupled plasma mass spectrometry. The potential dependence of the very low dissolution rates of Fe and Cr in the passive state was characterized. The selective dissolution of Fe was observed in the lower passive potential range, while Cr dissolved preferentially in the higher passive potential range. The discrepancy between the polarization curve and current from the Fe and Cr dissolution in the passive state was attributed to the formation of a passive film. The calculated film thickness was on the order of nanometers.
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.
