Corrosion inhibition in anti-corrosive coatings and the role of the inhibitive pigment

Języki publikacji

Abstrakty

Spektroskopia impedancyjna jest techniką szeroko stosowaną w badaniach inhibitorów i powłok. W artykule po krótkim omówieniu roli pigmentów antykorozyjnych (inhibitujących) w powłokach oraz wpływu samej powłoki na inhibitowanie korozji wyprowadzono model elektrochemiczny w celu obliczenia przewidywanej elektrochemicznej impedancji powłoki zawierającej inhibitor. Przedyskutowano wpływ inhibicji anodowej i katodowej na obserwowane widma impedancyjne, prawdopodobieństwo rejestrowania takiego inhibitowania przez system powłokowy za pomocą spektroskopii impedancyjnej oraz, w konsekwencji, warunków, w których takie inhibitowanie może pomóc w zmniejszaniu postępu korozji. W oparciu o te zasady przedstawiono nową technologię inhibitora nie zawierającego cynku i jego charakterystykę.

Impedance spectroscopy has been a widely used technique in the study of inhibitors and coatings (8-13). Following a brief survey on the role of inhibitive pigments in coatings and the influence of the coating itself on inhibition, the present paper will briefl y introduce an electrochemical model for purposes of calculating the expected electrochemical impedance of a coating containing an inhibitor. The influence of anodic and cathodic inhibition on observed impedance spectra, the likelihood of observing such inhibition from within a coating environment by means of impedance spectroscopy and as a consequence, the conditions under which such inhibition can aid in reducing the extent of corrosion will then be discussed. On this basis, approaches to newer zinc-free inhibitor technology will be introduced and some of its characteristics described.
