Microcapsule-based systems have now been cleveloped which contain self-healing and protective agents that can fully heal small-scale damage and prevent undercutting of the coating where larger scale damage is prevent. This effectively entends maintenance cycles on metal structures. Note de contenu : - Examples of non-autonomic healing in materials
- Autonomic healing requires a different approach
- The economic case for self-healing coatings
- Hexavalent chromium : an early self-healing system
- Using self-healing to improve protective coatings
- Self-healing of small-scale cracking demonstrated
- Dealing with coatings damage on larger scales
- Life extension in protective coatings
- Salt spray test confirms self-healing performance

Titre : Mica/polypyrrole (doped) composite containing coatings for the corrosion protection of cold rolled steel Type de document : texte imprimé Auteurs : Niteen Jadhav, Auteur ; Takeshi Matsuda, Auteur ; Takeshi Matsuda, Auteur ; Victoria Gelling, Auteur Année de publication : 2018 Article en page(s) : p. 363-374 Note générale : Bibliogr. Langues : Américain (ame) 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.

Spectroscopie des rayons XIndex. décimale : 667.9 Revêtements et enduits Résumé : Micas/polypyrroles (PPys) doped with molybdate, p-toluene sulfonate, dodecyl benzene sulfonate, and 2-naphthalene sulfonate composite pigments were synthesized by chemical oxidative polymerization and characterized in coatings for corrosion protection on cold rolled steel substrate by various electrochemical techniques. Synthesized composite pigments were characterized for morphology by scanning electron microscopy, which indicated physical formation of PPy on the surface of mica. Chemical composition of the composite pigments was analyzed by X-ray photoelectron spectroscopy which chemically confirmed doped PPy formation on the mica surface. Coatings were formulated at 20% pigment volume concentration (composite pigments or as-received mica pigment) and were applied on cold rolled steel substrate. Coatings were exposed to salt spray test conditions (ASTM B117) for 30 days and were periodically assessed for corrosion with electrochemical impedance spectroscopy (EIS), open circuit potential (OCP), and potentiodynamic polarization. EIS and circuit modeling results demonstrated higher coating resistance (R c) for mica/PPy (doped) composite coatings as compared to as-received mica pigment containing coating after 30 days of salt spray exposure. Lower current density and more positive corrosion potential values were observed for mica/PPy (doped) composite coatings as compared to mica pigment-based coating in potentiodynamic polarization measurements, indicating improved corrosion protection for cold rolled steel substrate. OCP measurements revealed more positive values for mica/PPy (doped) composite coatings as compared to mica pigment-based coating suggesting superior corrosion protection for mica/PPy (doped) composites.

Spectroscopie d'impédance électrochimiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Electrochemical impedance spectroscopy (EIS) is used to measure deterioration in a coating exposed to corrosive conditions. However, the standard test procedures are subjected to errors induced mainly by edge effects. A new test cell avoids this and allows EIS tests to be carried out non-destructively on the actual test panels used in salt spray and accelerated weathering tests.

Providing the necessary level of protection in a single layer and as a VOC-conform water-borne coating involves complex formulation, however, a phosphated surfmer may offer one solution. A nanostructured and phosphatised monolayered coating withstands rigorous testing. Note de contenu : - Surfmer creates phosphated passive layer
- Colour measurement may indicate phosphatisation
- Enhanced corrosionprotection of passive interface
