Abstract
This study investigates the impact of magnetic nanoparticle (MNP) size and concentration on the microbiologically influenced corrosion (MIC) of X70 steel, employing electrochemical tests, microscopic characterization, and sulfate concentration measurements. The results show that a 50 ppm concentration of MNPs increased the MIC rate by 122.1 %, with particle size having a minimal effect. High concentrations of MNPs significantly reduced anodic electron transfer resistance and enhanced cathodic consumption, thereby accelerating extracellular electron transfer (EET)- mediated MIC of X70 steel. These findings offer crucial insights into the role of magnetite in MIC mechanisms and provide a scientific foundation for improving the management of corrosion in oil and gas pipelines.
期刊介绍：
Electrochimica Acta is an international journal. It is intended for the publication of both original work and reviews in the field of electrochemistry. Electrochemistry should be interpreted to mean any of the research fields covered by the Divisions of the International Society of Electrochemistry listed below, as well as emerging scientific domains covered by ISE New Topics Committee.
