Formability of organic coatings—an electrochemical approach

Protection of copper against corrosion in simulated urban rain by the combined action of benzotriazole, 2-mercaptobenzimidazole and stearic acid

“…To fit the experimental data for modified copper samples, an approach has been taken that has been used for polymer-coated metals [44,45], oxide or mixed oxide/inhibitor polymer complexes on metal surfaces [10,11,27,31,[46][47][48] and self-assembled inhibitor layers of alkenthiols [33,49,50], aromatic thiols [51,52], dodecanethiol [35], dodecyl mercaptan [34], n-tetradecanoic acid [53] and potassium decanoate [54] on copper. The self-assembled layers were formed mainly by pre-treatment of an acid etched ground copper sample in an ethanol solution of inhibitor and then measured in test solution [33][34][35][49][50][51][52][53].…”

A forming limit curve for the corrosion resistance of coil-coatings based on electrochemical measurements

“…6 shows the evolution of the parameters with time of immersion for a set of samples with uniaxial strain. Results for the three modes of deformation are reported in references [9,10]. Y 0,f increased with time up to a plateau.…”

“…b) Film resistance, R f . In our work [9,10,18,19] this proved to be the most reliable parameter to evaluate the degradation of painted metals, being sensitive to the effects of mechanical deformation and showing a regular evolution with the time of immersion. It correlated well with the macroscopic and microscopic degradation of the samples.…”

“…These results are given as representative examples and a detailed analysis of the impedance of samples with uniaxial, biaxial and plane strain can be found in Refs. [9,10].…”

Erratum to: On the reduction of gloss property of organic coated sheet metals after forming

“…Out-plane stresses are the reasons for losing adhesion and may lead to a debonding effect between two layers. On the other hand, large plastic strains in the substrate cause the loss of adhesion at the interface and may also lead to delamination in further processing, see [3,[9][10][11][12]. In addition, residual stresses in the coating resulting from plastic strains in the metal substrate may lead to an additional shear stress at the interface which is the cause of the severe defect of the [12].…”
