The influence of cyclic potential pulse on the local corrosion of X70 pipeline steel in the electrolytes with pH close to neutral
The effect of cyclic potential pulse (CIP) on the local corrosion of X70 pipeline steel in the solutions with various compositions was investigated. Local corrosion of steel increases with an increase in the duration of the cathode half-cycle of the CIP, in the presence of a promoter of hydrogen absorption and with an increase in the concentration of chloride and bicarbonate ions. A quantitative indicator is proposed, which determines the intensity of local corrosion under CIP
