Abstract
Rare earth (RE) has been demonstrated to have a series of positive effects on performance of bearing steel. In this study, we propose a new mechanism that RE element can enhance the corrosion resistance of bearing steel under atmospheric condition by promoting the formation of a thicker surface oxide film with a greater thickness in the inner protective layer which consists of Fe3O4 and Cr2O3. Such an evolution is primarily associated with the dissolved RE element in steel matrix. Besides, EIS data regression can provide a way to quantify the corrosion resistance evolution in surface oxide film on steel substrates.
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.
