Resumo
The effect ofbenzotriazole (C6H3NsJ as a corrosion inhibitor for type 304 stainless steel in
2M H2S04 has been studied using weight loss experiments, anodic and cathodic potentiostatic
measurements, atomic emission spectrometry, and optical and scanning electron
microscopy. Benzotriazole acted as a corrosion inhibitor over the entire range of potentials
studied, from - 625 to + 1250 m V with respect to a saturated calomel electrode, and did
not promote selective alloy dissolution. The protective film was stable and adherent and
obeyed the Langmuir isotherm, while values of the equilibrium adsorption constant suggested
chemical adsorption. The maximum coverage obtained was 0·97 for stirred solutions
and 1·0 for unstirred solutions, these values being associated with partial dissolution and
lack of dissolution of inclusions respectively.
