More Information
Summary:A coated metallic substrate includes a corrosion inhibition coating material including a corrosion inhibition compound that is a linear polymer including at least four inhibitor groups. The at least four inhibitor groups are linked together with labile linkages. Each of the labile linkages is independently selected from the group consisting of a disulfide bond and a metal-sulfide bond. Each of the labile linkages dissociates in response to a corrosion stimulus to produce a disassociated inhibitor group having an active thiol group. The coated metallic substrate further includes a metallic substrate. The corrosion inhibition coating material is cured onto the metallic substrate. Each dissociated inhibitor group is configured to adhere to the metallic substrate to form a passive layer on the metallic substrate. Un substrat métallique ayant un revêtement comprend un matériau de revêtement d'inhibition de corrosion comprenant un composé d'inhibition de corrosion qui est un polymère linéaire comprenant au moins quatre groupes d'inhibiteurs. Ces derniers sont liés par des liaisons labiles. Chacune des liaisons labiles est sélectionnée indépendamment à partir du groupe constitué d'un lien de disulfure et d'un lien de sulfure métallique. Chacune des liaisons labiles se dissocie en fonction d'un stimulus de corrosion pour produire un groupe d'inhibiteurs dissocié ayant un groupe thiol actif. Le substrat métallique ayant un revêtement comprend également un substrat métallique. Le matériau de revêtement d'inhibition de corrosion est durci sur le substrat métallique. Chaque groupe d'inhibiteurs dissocié est configuré pour adhérer au substrat métallique pour former une couche passive sur le substrat métallique.
