Abstract Both the holidays crossing through the polyolefin t ape coating and the loss of adhesion of polyolefin tape result in poor protectiv e capabilities of coating.Galvanostatic step technique and electrochemical imped ance spectroscopy were used to investigate the electrochemical behavior of carbo n steel with coating of different failure.The difference of the voltage r esponse curves for the samples with different coating failures was observed and the ratio of the coating resistance to the gross resistance was proposed to dete rmine the coating condition.The degrading process of polyolefin tape immersed in to tap water was studied and it was found that the adhesion of coating degraded quickly for tape coating having holidays.The study demonstrated that in addition to EIS technique,galvanostatic step technique is another suitable method in stu dying coating-metal system.

Key words: polyolefin tape coating coating failure galvanostatic step technique EIS
