Abstract

In this work, linear sweep voltammetry and zero resistance ammeter meth- ods using rotating disk electrodes were utilized to determine and char- acterize the galvanic interaction be- tween mineral particles and AISI 1020 carbon steel immersed in seawater for a combination of exposed areas and electrode rotating rates. Galvanic cur- rent 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 concen- trate suspensions during mineral pro- cessing operations.
