Abstract

When the electrical potential criterion for cathodic protection has been determined the engineer is faced with the problem of achieving this at every part of the structure. Lack of spread of protection is caused by a change in potential of either or both the metal and the electrolyte. This change may be attributed to three factors: cathode control where the metal potential varies, electrolyte control where the electrolyte potential varies by virtue of the cathode shape and positional control where the anode proximity controls the spread. These factors can be analysed and models made to reproduce the conditions so that an economical design may be achieved.
