摘要：

Electrochemical impedance spectroscopy (EIS) was used to study the effect of residual chlorine and ammonia on the corrosion behaviour of carbon steel, UNS C71500 and UNS N06030 in seawater. Typical interfacial impedance results showed slightly shifting to resistive behaviour for the three alloys upon the addition of 5 ppm. of chlorine to seawater. However, a slight shift of the impedance towards less resistive behaviour for the three alloys was observed when 5 ppm of ammonia was added to the seawater.
