“…This resulted in the increase of pH beneath the coating, causing the coating's disbondment from the metal surface. 37 Furthermore, the corrosion products created at the interface of coating/ metal could lead to the further decrease in adhesion of coating to the metal substrate. The adhesion loss of the polyurethane coatings was calculated according to Equation (2) …”

Fe 2 O 3 nanoparticles were modified with 3-amino propyl trimethoxy silane (APTMS) by a sol-gel method. The surface chemistry of the Fe 2 O 3 nanoparticles was studied by Fourier transform infrared spectroscopy, which confirmed the successful grafting of the organic functional groups of APTMS onto the nanoparticle. Polyurethane composites were prepared by the incorporation of 1, 2, and 3 wt% of modified and unmodified Fe 2 O 3 nanoparticles. The surface morphology of the composites and distribution of the nanoparticles were investigated by field emission scanning electron microscopy. The composites were applied on the mild steel substrates. The adhesion strength of the composites was determined by a pull-off adhesion tester. The effect of nanoparticles on the electrochemical and corrosion behaviors of the coatings was investigated in a 3.5% NaCl solution, using electrochemical impedance spectroscopy and a salt spray test. Results showed that incorporation of 2 wt% modified Fe 2 O 3 nanoparticles significantly improved the corrosion resistance and recovery adhesion strength of the polyurethane coating compared to the blank coating and the one containing unmodified nanoparticles.

“…They found that the adhesion strength of the epoxy coating was significantly increased and the cathodic delamination was decreased after surface treatment by zirconium conversion layer. In our previous study [28] the effects of adding poly(vinyl) alcohol (PVA) to the phosphate conversion coating on the anticorrosion and adhesion properties of the epoxy coating were studied. It was found that PVA could significantly enhance the epoxy coating adhesion properties and corrosion protection performance on the mild steel through affecting the surface free energy and the morphology of the conversion coating.…”

“…Moreover, the positive effect of zinc aluminum hydrotalcite intercalated with benzothiazolylthio-succinic acid on the cathodic delamination resistance of epoxy coating was reported by Hang et al [30]. Interestingly, the influence of either direct or indirect addition of corrosion inhibitors to the conversion coatings or any pretreatments on the cathodic delamination of overlaying polymeric films has been studied in some literature [24,31,32]. Ramezanzadeh et al [31] achieved an improved cathodic disbonding and adhesion properties through application of epoxy coating on the steel substrate covered by zinc phosphate conversion coating containing poly(vinyl) alcohol.…”

This study is aimed to evaluate the effect of concentrated benzimidazole (BIM) on the cathodic disbonding (CP) of an epoxy coating applied on steel substrate. For this purpose, the polymeric coatings, formulated with different concentrations of BIM (0 wt.%, 0.5 wt.%, 0.75 wt.%, and 1 wt.%, were subjected to the CP test at the potential of −1.2 V vs. Ag/AgCl during 24 h immersion in 3.5 wt.% NaCl solutions. The optimum formulation was found through taking advantage of the CP test results, FESEM/EDX, and EIS data. Moreover, a pull-off test was used to measure the wet adhesion strength. For insight into the inhibition function of the organic inhibitor, the behavior of steel in the sodium chloride solutions, with and without BIM, was compared using EIS and surface analysis.
