Abstract

En forbrukbar anode for korrosjonsbeskyttelse av et byggverk til havs har en sammensatt oppbygning hvor et første anodisk material (2), som utgjør et ytre belegg på anodens kjerne (1), har et mer negativt elektrokjemisk potensial enn det material som utgjør byggverket til havs som skal beskyttes. Det anodiske material forsynes i sin tur med et ytre belegg fremstilt fra et andre anodisk material (3) med et enda mer negativt elektrokjemisk potensial enn førstnevnte anodiske material (2). Det er videre angitt noen typer anodisk material og en framgangsmåte for fremstilling av en sådan forbrukbar anode.A consumable anode for corrosion protection of an offshore structure has a complex structure where a first anodic material (2), which constitutes an outer coating on the anode core (1), has a more negative electrochemical potential than the offshore material which must be protected. The anodic material is in turn provided with an outer coating made of a second anodic material (3) with an even more negative electrochemical potential than the former anodic material (2). Further, some types of anodic material and a process for making such a consumable anode are disclosed.
