    Description / Table of Contents: 2-Benzimidazolethiol as a corrosion inhibitor for copper in acetic acid and hydrochloric acid solutionsAn attempt has been made to evaluate the inhibitive power of 2-benzimidazole-thiol for corrosion of copper in acetic acid and hydrochloric acid solutions. The substance acts as an excellent inhibitor for copper in both the systems. This inhibitive action of 2-benzimidazolethiol can be attributed to chelate formation with the metal ion.Polarization measurements reveal that the inhibition is governed principally by the cathodic polarization.
    Notes: 2-Benzimidazolthiol inhibiert die Korrosion von Kupfer sowohl in Essigsäure als auch in Salzsäure. Die Wirkung beruht auf Chelatbildung mit den Metallionen. Aufgrund von Polarisationsmessungen ist die Inhibierung überwiegend kathodisch kontrolliert.

    Description / Table of Contents: Einfluß von Azolen als Korrosionsinhibitoren für Aluminium 3003 in Trichloressigsäurelösungen2-Mercaptobenzthiazole, 1,2,3-Benztriazol, 2-Methylbenzthiazol sowie Indol sind wirksame Inhibitoren der Korrosion von Aluminium 3003 in 0,1 n Trichloressigsäure. Mit Ausnahme von 1,2,3-Benztriazol, das einen Inhibitor vom Mischtyp darstellt, sind die anderen Substanzen kathodisch wirksam. Die Einführung von -SH-Gruppen erweist sich als günstig. Die Wirkung der Inhibitoren dürfte darauf beruhen, daß die betreffende Substanz an der Metalloberfläche adsorbiert wird und dort stabile Verbindungen zwischen Metall und Schwefel bzw. Stickstoff gebildet werden. Die Bindung mit Schwefel ist dabei stärker.
    Notes: 2-Mercaptobenzthiozole, 1,2,3-benztriazole, 2-methylbenzthiazole and indole are efficient inhibitors of the corrosion of aluminium 3003 in 0.1 N trichloroacetic acid. With the exception of 1,2,3-benztriazole which is a mixed type inhibitor the other compounds are cathodic inhibitors. The introduction of -SH-group is favourable. The effect of the inhibitors may be due to the fact that the particular substance is adsorbed to the metal surface where stable bonds are formed between metal and sulfur and nitrogen respectively. The metal-sulfur bond is stronger.
