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.
