ZincIndex. décimale : 667.9 Revêtements et enduits Résumé : The degradation of a zinc-rich epoxy primer/acrylic polyurethane coating system on carbon steel was studied in the simulated marine atmospheric solution (0.05% NaCl), industrial atmospheric solution (0.35% (NH4)2SO4), and marine-industrial atmospheric solution (0.05% NaCl + 0.35% (NH4)2SO4), by electrochemical impedance spectroscopy, Fourier transform infrared spectroscopy, and scanning electron microscopy methods. The influences of the soluble contaminants in the atmospheres, including chloride ions, sulfate ions, and ammonium ions, on the coating failure mechanism were compared and analyzed. The results showed that the degradation speed of the coating system in three simulated atmospheric solutions is in the following order: simulated marine atmosphere > simulated marine-industrial atmosphere > simulated industrial atmosphere. The degradation is mainly related to the permeation rate of the water through the coating. The aggressive ions, basic cations, and the property of the corrosion products also have influences on the degradation process. The alternating temperature environment (45°C 12 h + 25°C 12 h) could increase the degradation speed of the coating and the difference of the speed in the three solutions.

Polyméthacrylate de méthyleLe poly(méthacrylate de méthyle) (souvent abrégé en PMMA, de l'anglais Poly(methyl methacrylate)) est un polymère thermoplastique transparent obtenu par polyaddition dont le monomère est le méthacrylate de méthyle (MMA). Ce polymère est plus connu sous son premier nom commercial de Plexiglas (nom déposé), même si le leader global du PMMA est Altuglas International9 du groupe Arkema, sous le nom commercial Altuglas. Il est également vendu sous les noms commerciaux Lucite, Crystalite, Perspex ou Nudec.
Spectroscopie d'impédance électrochimique
Spectroscopie RamanIndex. décimale : 667.9 Revêtements et enduits Résumé : In the maritime industry, stainless steel corrosion resistance requires further surface improvement and further enhanced protection using surface coatings. In this study, an engineered copolymer of polyvinylidene fluoride (PVDF) with polymethylmethacrylate (PMMA)-blended coating was found to provide outstanding corrosion resistance for metal surfaces affording protection against severely corrosive marine environments. Electrochemical measurements indicate that corrosion protection of 316 stainless steel was drastically increased when utilizing the KP blend (a combination of PVDF + PMMA), producing a new set of corrosion properties and morphological characteristics. The corrosion protection of the KP coating proved to be very effective in reducing the passive region current density from 2.19 × 10−5 A/cm2 (for bare stainless steel) to 2.63 × 10−10 A/cm2 and the breakdown passive region potential at 0.25 V. This was followed by a significant decrease in corrosion rate, when compared to pure PMMA and PVDF films, during exposure to artificial marine seawater. With the KP film, impedance measurements surpassed those of other films, with a noticeable nonpeak straight line in the phase angle diagram. Optical observation showed that corrosion pits and delamination areas existed under the coatings.

Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : This article reports on a comparative study on the corrosion resistance of low-carbon steel substrates pretreated with different silane solutions and painted. The pure silanes used to pretreat the steel panels were 3-aminopropyltriethoxysilane (?-APS), 3-glycidoxypropyltrimethoxysilane (?-GPS), and bis(3-triethoxysilylpropyl)amine. The study also considered other silane solutions with ureido, amino, and epoxy organofunctional groups, and two bis-functional silanes: bis(?-trimethoxysilylpropyl)amine (BAS) and 1,2-bis(triethoxysilyl)ethane (BTSE). A conventional phosphate-type pretreatment was also applied for reference purposes. The pretreated panels were then finished with an alkyd/polyester aminoplast base paint. As a branch test, an acrylic/urethane paint was also applied. Different tests were conducted to evaluate the anticorrosive ability of the different silane/paint systems: outdoor exposure in an atmosphere of moderate aggressivity; accelerated corrosion test (salt fog test); and electrochemical impedance spectroscopy (EIS). The results show that the steel pretreated with certain silanes, especially ?-APS, yields similar results to steel subjected to conventional phosphate pretreatment.
