- Abstract
- This paper focuses on the anticorrosive behaviour of surface films formed by different benzotriazole alkyl
derivatives on a Cu6Sn bronze (B6), whose composition is similar to materials used for outdoor artefacts.
Some alkyl derivatives of the 1,2,3-benzotriazole (BTA) as: 5-hexyl-1,2,3-benzotriazole; 5-dodecyl-1,2,3-
benzotriazole and [5-(1-undecyl)dodecyl]-1,2,3-benzotriazole were synthesized in order to investigate the
influence exerted by the aliphatic chain on the inhibiting properties of the base molecule (BTA) toward
bronze corrosion. The protective efficiency of the organic films, after a preliminary evaluation by
electrochemical measurements, was determined by thin layer activation (TLA) and gravimetric techniques
on the samples submitted to artificial weathering experiments in acid rain. For TLA measurements a ?-
emitting radio nuclide 65Zn (t1/2=244 days), used as a corrosion tracer, was produced on the bronze surface
by a high energy proton beam. At the end of artificial weathering exposures the radioactivity recovered on
the bronze surface, once it was treated with a picking solution, allowed determination of the thickness loss.
All the results arising from the different techniques, used in this study, show that BTA molecules bearing long
aliphatic chain act as the best corrosion inhibitors. (literal)
