Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Water-borne industrial coatings require the addition of dis¬persing agents in order to form a smooth, defect-free film. However, the hydrophilic sections in these molecules can often impair the ability of the coating to resist corrosion. A new dispersant technology delivers excellent corrosion resistance while maintaining dispersion performance. Note de contenu : - Corrosion reactions

Spectroscopie de photoélectronsIndex. décimale : 667.9 Revêtements et enduits Résumé : This article presents the materials, methods, and main results obtained in an experimental study which was aimed at the development of alternative environmentally friendly pretreatments to chromium for tinplate food can applications. A commercial tinplate was used as substrate. Chromium, titanium, zirconium, cerium, and oxalate-based pretreatments were studied. The characterization of the pretreated tinplate specimens was carried out using scanning electron microscopy (SEM), energy dispersive X-ray (EDX), and X-ray photoelectron spectroscopy (XPS) techniques. The corrosion behavior of the pretreatments was evaluated using electrochemical measurements and exposure tests in several synthetic media. The results obtained led to the conclusion that, among the different pretreatments studied, the best performance was obtained with titanium and cerium compounds.

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Zn–Al layered double hydroxide (LDH) intercalated with various corrosion inhibitors namely vanadate (E1), 2-mercapto benzothiazole (E3), molybdate (E7), phytic acid (E8) and 8-hydroxyquinoline (E9) was dispersed in a hybrid sol–gel silica matrix sol. Bilayer coatings with configurations E3|E1, E7|E1, E8|E1 and E9|E1 were generated on aluminum alloy AA 2024-T3 substrates using the inhibitor intercalated LDH modified sols by dip coating technique followed by UV curing and thermal curing at 80°C for 1 h in air. Corrosion resistance of coatings deposited from matrix sol with and without inhibitor intercalated LDH was studied by electrochemical impedance spectroscopy, potentiodynamic polarization after exposure to 3.5% NaCl and salt spray tests, results of which were compared with those of uncoated and chromated substrates. A non-chromated primer was applied on the sol–gel coated substrates. Adhesion of the coatings to the substrate and to the primer was evaluated by peel-off tape test and found to be rank 5. The sol–gel coated substrates did not exhibit corrosion during salt spray tests. Electrochemical tests showed that all the sol–gel coated substrates exhibited superior corrosion resistance when compared to bare and chromated substrates. More specifically, coatings generated using the corrosion inhibitors phytic acid and 8-hydroxy quinoline intercalated Zn–Al LDH were seen to render maximum corrosion protection, exhibiting two orders of magnitude lower corrosion currents than bare substrates and one order lower corrosion current than chromated substrate, after 120-h exposure to 3.5% NaCl solution.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Self-reparable microcapsules which can repair microcracks in the coating matrix and effectively inhibit the corrosion at the substrate/coating interface during service have been evaluated. The main objective was to fabricate an innovative pH-responsive permeability-switching polyurea-formaldehyde (PUF)-based microcapsule laden with 8-hydroxyquinoline (8-HQ) as the core material for the production of smart epoxy coating for the long-term protection of Al alloys. Combined improved barrier, active, and self-repairing properties indicating sort of triple-action corrosion mitigating ability of the modified epoxy-based smart coating was demonstrated by electrochemical impedance spectroscopy and scanning electron microscopy. The results indicate that the self-repairing action occurs via two mechanisms: firstly, by the initiation of chain mobility at the modified coating defects on heat treatment. Secondly, by the crosslinking of the swelled hydrogel present in the PUF shell wall via the various polymer–polymer interactions. The active corrosion protection was due to the (smart) pH response–release ability of the encapsulated inhibitor (8-HQ) with an increase in corrosion degree. Meanwhile, the even dispersal of the fabricated microcapsule with its intrinsic rough surface in the epoxy coating matrix contributed to the improved barrier and adhesive properties.
