Abstract
Anodo sacrifiziale per la protezione anticorrosiva di strutture offshore, costituito da una struttura composita in cui un primo materiale anodico che riveste esternamente il supporto dell'anodo stesso, detto materiale avendo un potenziale elettrochimico più negativo di quello del materiale della struttura offshore da proteggere, è a sua volta rivestito esternamente da un secondo materiale anodico a potenziale elettrochimico ancor più negativo di quello del primo materiale.Vengono inoltre specificati alcuni tipi di materiale anodico nonché un procedimento per la realizzazione di un siffatto anodo sacrifiziale.
