Resumen
In this work, linear sweep voltammetry and zero resistance ammeter methods using rotating disk electrodes were utilized to determine and characterize the galvanic interaction between mineral particles and AISI 1020 carbon steel immersed in seawater for a combination of exposed areas and electrode rotating rates. Galvanic current and potential values obtained from both methods were compatible. The experimental galvanic corrosion density values, which are much larger than those of non-galvanic corrosion, reveal a serious threat to pipelines and infrastructure that handle concentrate suspensions during mineral processing operations
