The distribution of the electricfield and of the current density in case of electrocorrosion countermeasures using thesacrifice anodes technique
Abstract
An electric field oriented from sea water towards the ship, can develop an extraction work. The corrosion process was thus diminished, by a change in the ship’s hull mass, due to a continuous tore of the material from its bulkheads. The issue that arises is an attenuation of the extraction electric forces and a reduction in the process of mass changing. This problem can be solved by using an impressed electric field, opposite to the one developed during the corrosion process, field which can minimize the extraction work generated by this process.
