Abstract
This paper reports the behavior of galvanic anodes for cathodic protection in natural sea water under anaerobic and aerobic conditions. This work is a part of a research on the study of cathodic protection conditions and anodes behavior in a simulated deep-water environment. A series of tests, in aerobic and anaerobic conditions, were performed on carbon and stainless steel in natural sea water. It has been confirmed that the protection potential in anaerobic condition has to be lower than –800 mV SCE; the protection current density is not highly influenced by the anaerobic environment; the anodic efficiency vary with the kind of alloy and their impurity concentration.
