Korrosion und kathodischer Korrosionsschutz von unlegiertem Stahl in Sandböden

Abstract: Ein kathodischer Korrosionsschutz lie@ dann vor, wenn das Schutzpotentialkriterium erfiillt ist. Dabei muB das RohrlBoden-Potential negativer als das Schutzpotential sein. Bei ubenvachungsbedurftigen Anlagen ist dies regelmiiSig nachzuweisen. Schutzpotentiale werden in Regelwerken angegeben (z.B. DIN 30676) und kBnnen in Zweifelsfallen experimentell ermittelt werden. Fur Erdboden gilt im allgemeinen das Schutzpotential von Uol/cuso, = -0,85 V. I m Falle hochohmiger, salzhaltiger SandMden mit geringer Feuchtigk… Show more

“…8 As long as the pH is increased, passivity and hence corrosion protection is achieved under such conditions. 8 This immediately explains the corresponding protection criteria determined by Funk, et al, 20 that are stated today in ISO 15589-1.…”
