Corrosion Fundamentals

Cathodic Protection

Cathodic protection is an electrical means of corrosion control. Cathodic protection can be applied using sacrificial (galvanic) anodes or by means of more complicated impressed current systems.

Fishing Boat With Sacrificial Zind Anodes

This Louisiana fishing boat has sacrificial zinc anodes welded to the hull to slow down corrosion. No pattern is apparent to how the anodes were attached-the design philosophy seems to be that if one anode is good, more is better.

The Kennedy Space Center's cathodic protection research has concentrated on the use of sacrificial and impressed current systems for minimizing corrosion of embedded steel in concrete structures.
