► Cathodic disbondment and oxide lifting are attributed to the coating delamination. ► Coating delamination is accelerated effectively by the pulsed potentiostatic test. ► The Rct of the coated system is closely related to the delamination area. The electrochemical degradation of polyethylene coated...
