摘要

Corrosion poses a significant challenge to the longevity and performance of steel pipelines, particularly those used in hydrocarbon transport. This study investigates the impact of burnishing on the corrosion resistance of API 5L X52 steel, a material widely used for high-pressure applications. Burnishing, a surface treatment method, is compared with traditional machining to assess its effectiveness in improving corrosion resistance. High Yield Strength (HYS) steel grade X52-Q was subjected to various burnishing conditions, characterized by different feed rates and number of passes. Corrosion resistance was evaluated using electrochemical tests, focusing on parameters such as corrosion potential (E_cor), corrosion current density (I_cor), and polarization resistance (R_p). The results indicate that burnishing significantly enhances corrosion resistance compared to machining, with polarization resistance (R_p) increasing by 65.98% to 442.53%. The most notable improvement was observed with a 400-mm/min advance and three passes, showing that the number of passes has a more pronounced effect on corrosion resistance than the advance speed. A linear regression model was developed to predict R_p based on burnishing parameters, highlighting the critical role of the number of passes. These findings underscore the benefits of burnishing in extending the service life of API 5L X52 steel pipelines, offering both economic and operational advantages by enhancing durability in corrosive environments.
