“…Besides passivation of the substrate surface (inhibitive effect) and sacrificial protection (galvanic effect), barrier protection is one of the basic protective mechanisms of anticorrosive organic coatings [1]. The protective properties of barrier coating systems are known to depend on numerous factors, including the material properties of the polymer binders, pigmentation, layer structure and thickness, type of corrosive environment, type and pre-treatment of the substrate, the presence of initial defects or impacts etc.…”

“…[1]. Although the general mechanisms preceding coating failure are basically understood, the exact cause and nature of coating breakdown is still in dispute [1]. The processes involved in coating failure are transport of water, ions and oxygen followed by adhesion loss and corrosive chemical reactions.…”

“…The transport processes include water diffusion through the polymer matrix, along the coating-metal interface or through cracks [2 -4] as well as migration of ions [1 -3, 5]. These mechanisms are assumed to be the ratedetermining steps for the decrease in adhesion strength between coating and substrate [1,6] ("weak wet adhesion"), cathodic disbonding, blistering, delamination [1 -3, 5, 7 -11] and rust creep [12].…”

Scanning acoustic microscopy (SAM) was used to investigate disbonding, delamination and blister formation in polymer coatings for different layer structures and initial defect depths during exposure to a corrosive environment. The time evolution of disbonding and blister initiation and their growth was investigated by analysing the SAM images exposure to an electrolyte solution (Harrison solution). From investigations of a model system of coatings on steel substrates, it was possible to differentiate between water and/or ion transport (i) through the coating and (ii) along the coating-steel interface. For samples without clear coat randomly distributed blisters appeared at the coating-steel interface after exposure to the electrolyte solution, irrespective of the location of initial defects. The random distribution of growing blisters is related to diffusion of water and/or ions through the coating and "nucleation" at weak points of the substrate or within the polymer. For samples with clear coat a propagating migration front along the coating-steel interface of 3-4 µm height -starting from initial defects -was detected. The linear propagation of this front cannot be explained by Fickian diffusion. Therefore, it is discussed in terms of an accelerated diffusion or crack growth kinetics. Since blistering starts only at sites, where the migration front has passed, the presence of a thin water layer at the coating-steel interface, the loss of adhesion and the following corrosive processes are prerequisites for the nucleation of blisters. The blister growth shows a square-root time dependence which was related to a diffusion controlled transport mechanism.
