Corrosion and protection of bridges (Part 2) / P. K. Kamani in PAINTINDIA, Vol. LXV, N° 3 (03/2015)
[article]
Titre : Corrosion and protection of bridges (Part 2) Type de document : texte imprimé Auteurs : P. K. Kamani, Auteur Année de publication : 2015 Article en page(s) : p. 117-123 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

Traîtements de surfaceIndex. décimale : 667.9 Revêtements et enduits Résumé : Painting on bridges has multifarious role : decoration, protection and functional. There have been lots of development in every sphere of painting system : surface preparation, primer to top coat, pain application equipments, etc. Environment, painting cost and performance of die coatings are the basic reasons behind the development of newer technology. New paint systems have been developed to meet low VOC requirement and facilitate painting comprise fewer layers compared to old paint systems having several layer of paints with high VOC. Present paint systems for bridges enable vert' long repair intervals. Painting conditions in workshops have improved considerably in the fast few years, and the risk of moisture condensing on the surface of steel before painting has been eliminated completely.

PhosphatesIndex. décimale : 667.9 Revêtements et enduits Résumé : In this article, the effects of two inorganic corrosion inhibitors, permanganate and phosphate anions, on morphology, composition, thickness, and corrosion resistance of the anodic film formed on 2024 aluminum alloy in sulfuric acid were investigated. Surface morphology of the oxide films were studied by field emission scanning electron microscopy. Electrochemical impedance spectroscopy and potentiodynamic polarization tests were conducted to assess the corrosion resistance of the coatings. These analyses showed that the presence of the mentioned inhibitors changed the coating morphology, especially in the case of phosphate ions. Corrosion results indicated that using inhibitors during the anodizing process increased the corrosion resistance of the anodized samples. The increases were approximately 81% and 97% for 0.05 M of permanganate and phosphate ions, respectively, compared with the anodized coatings in the absence of additives. An increase in the inhibitor concentration results in better corrosion resistance of the aluminum anodic layer.

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.

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : The author explains the increased amount of environmental legislation impacting on anti-corrosion coatings.
Since the early days of epoxy chemistry, traditionaly type 1 / polyamidoamine systems have dominated the field of corrosion protection. A range of characteristics including tolerant mixing ratio, extremely long pot life, enhanced mechanical properties and relatively short drying times plus excellent corrosion prperties, has ensured the continued success of this solvent-based coating solution. However, increased legislative pressure surrounding the use of Volatile Organic Compounds (VOC) is driving forward significant changes in the global coatings industry. Formulators are being urged to reduce the use of solvents in coatig solutions to help minimise detrimental effects on the environment and human health. National authorities, especially in Europe and North America have established several solvent reduction programmes to ensure applicators reduce VOCs in their coating products (EU Directive 1993/12 and 2002/42; SCADQMD (South Coast Air Quality Management Discrit)) regulations for wood, metal and architectural coatings. Private companies and industry groups have also agreed to reduce VOC output by setting limits for production lines and evaluating alternative environmentally friendly technologies including power coatings and high solid coatings. These changes are impacting on heavy duty, marine, automotive, aerospace and architecture markets where 'green' solutions are becoming the technologies of choice, replacing traditional solventborne products such as the traditional type 1 / polyamidoamine systems.
An alternative option for coating formulators looking to reduce the use of VOC whitout compromising the level of corrosion protection provided is high solid systels. These are typically defined as a solution with a solid volume content grater than 60%. The reduction in solvent content in high solid coatings results in a higher thickness and viscosity, which can cause issued with spray coating applications. Therefore, for formulators to reach lower lovels of VOC and still have a fluid coating system, a lower viscous resin adn/or hardener is required. Here the resin and hardener options available for coating formulators looking to specify high solid, VOC-free coating systems and retain all the performance and application requirements for corrosion protection applications, are discussed.Note de contenu : - Resin component in high solid systems
