Course Duration: 18 hours

Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell. A simple method of protection connects the metal to be protected to a more easily corroded “sacrificial metal” to act as the anode. The sacrificial metal then corrodes instead of the protected metal. For structures such as long pipelines, where passive galvanic cathodic protection is not adequate, an external DC electrical power source is used to provide sufficient current.

Topics covered include:
  • Corrosion ( meaning & causes )
  • Forms and types of corrosion 
  • Methods of corrosion protection
  • Concept of cathodic protection
  • Methods of cathodic protection
  • Measurements of cathodic protection 
  • Design of cathodic protection
  • Cathodic protection system
