Corrosion Module

Steel structures immersed in seawater can be protected from corrosion through cathodic protection. Se gli elettrodi sono progettati correttamente, medieranno l’assorbimento delle correnti parassite senza corrodere la struttura posta vicino a una sorgente di tali correnti, come una ferrovia.

Therefore, at the Naval Research Laboratory NRLresearchers are developing a method based on multiphysics simulation that will aid material designers in producing corrosion-resistant materials. Submarines create underwater electric potential UEP signatures when using corrosion protection systems. This model simulates atmospheric galvanic corrosion of an aluminum alloy in contact with steel.

Charge and oxygen transport are modeled in the concrete domain, where the electrolyte conductivity and oxygen diffusivity depend on the moisture content. Corrosion Protection of a Ship Hull Galvznica current cathodic protection is a commonly employed strategy to mitigate the ship hull corrosion where an external current is applied to the hull surface, polarizing it to a lower potential.
