Abstract
Corrosion of steel pipelines underneath a disbanded coating can be a serious problem because the corrosion often is difficult to control by traditional cathodic protection (CP) methods. The relatively high electrical-resistance path along the crevice between the disbanded coating and steel prevents penetration of adequate protection current.Pulse CP has been investigated over a wide range of frequencies with various peakamplitudes and duty cycles. No significant benefits were found over steady-state CP.
