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.
