Abstract
The penetration of cathodic protection potentials under disbonded pipe line coatings has been studied. A physical model based on laboratory d ata has been developed. In neutral-pH, low-conductivity trapped water, effective protection potentials were found to penetrate less than 10 cm (4 in.) into a simulated disbondment. The implications for general corrosion and stress corrosion cracking are discussed.
