Composite coatings containing 0.3% (mass) glass fiber and different contents of thiourea inhibitor were prepared. SEM was used to characterize the distribution character and dispersion effects of glass fiber and thiourea inhibitor in the coating. EIS was used to investigate the effects of glass fiber and thiourea inhabitor on inhibition behavior of the coating. EDS was used to characterize the element distribution in defect position of the coating. The results showed that the composite coating containing glass fiber and thiourea inhibitor had higher Rc , lower Qc and longer service life than blank coating. When adding 0.3% glass fiber and 0.6% thiourea inhibition to intermediate coating, the composite coating exhibited the best protection performance to Q235 steel.
