CORROSION

• Metals extracted from its primary ore (metal oxides) have a natural tendency to revert to that state under the action of oxygen and water.
• Corrosion is an electro-chemical process that involves the passage of electrical currents on a micro or macro scale by an “anodic” reaction.
• This reaction produces free electrons, which pass within the metal to another site on the metal surface (the cathode), where it is consumed by the “cathodic” reaction.
• Corrosion process is initially caused by: 
  • Difference in natural potential in galvanic (bimetallic) couples. Metallurgical variations in the state of the metal at different points on the surface.
• Oxygen rich areas become the cathode and oxygen depleted areas become the anode.

 

 

CATHODIC PROTECTION

• The principle of Cathodic Protection is in connecting an external anode to the metal to be protected and the passing of an electrical dc current so that all areas of the metal surface become cathodic and therefore do not corrode.
• The current is a result of the potential difference between the two metals.
• Causes a positive current to flow in the electrolyte, from the anode to the steel.
• Surface of the steel becomes more negatively charged and becomes the cathode.

• A Galvanic System requires: 
  i) Sacrificial anodes  
  ii) Direct welding to the structure or a conductor connecting the anode to the structure
