In simple terms, anodic protection is based on the formation of a protective oxide film on a metal surface, using externally applied current. This can only be accomplished if the metal has an active/passive transition state, as is found with nickel, titanium, iron, chromium and their alloys.

Anodic protection has particular advantages with regard to its applicability in extremely corrosive environments and the low current requirements. It is therefore generally found only in high concentration acid or alkali environments and is limited to specific metal / electrolyte combinations.

Anodic protection operates in a precise range of potentials and requires careful control. Out of range potentials can result in accelerated corrosion.

Isinyithi is one of few companies with both the expertise and experience in successful Anodic Protection system design and implementation.
