Abstract
An electrochemical method for field monitoring of protective properties of organic coatings in seawater environment includes: Through the method, we reached to map the deteriorating state of the organic coating to metal substrate for coating on the activity of area of the effect of stripping state recognition, resolved to organic anticorrosive coating anticorrosion performance timely and accurate assessment of the actual problem, achieved by monitoring the anode current to evaluate the organic coating stripping area. This method is scientific and has good technics and broad application value.
