Abstract: A series of inorganic zinc-rich coating samples with various zinc contents was prepared by brush and spray methods to investigate the corrosion resistant performance of zinc-rich coating in oilfield produced water system, sour oilfield produced water system (pH value of 4) and marine atmosphere. Results showed that the acid resistant property of zinc-rich coating was not good enough, coating having a mass ratio of inorganic resin/zinc powder equaled 1:2.6, exhibited the best corrosion resistant property. By analyzing the morphology of sample prior and post to corrosion, comparing the XRD pattern of corrosion product, the phase and structure of the corrosion product was determined. It was found that Zn5(OH)8Cl2·H2O was the main corrosion product, under high chlorine conditions, insoluble Zn5(OH)8Cl2·H2O could inhibit further corrosion, soluble zinc acted as sacrificial anode for the cathodic protection of steel.
