  • System and method for analyzing cathodic protection current shielding of a coating
    Patent number: 11467083
    Abstract: A system, apparatus, and method for analyzing cathodic protection (CP) current shielding of a coating are provided. The system includes: a test cell configured to have a coating film disposed therein and to be filled with electrically conductive solution surrounding the coating film; an electrical resistance (ER) probe mounted through a port of the test cell; and a potentiostat configured to: apply potential to the test cell to thereby polarize a sensing element of the ER probe such that the ER probe is configured to measure data indicative of a corrosion rate of the sensing element when the coating film is disposed within the test cell and while a CP current flows through the sensing element; and measure a current density through the sensing element in order to indicate an extent of CP current shielding of the coating film.
