Abstract

The performance of the electrochemical technique first developed by Mattsson and Kučera, has been studied under long term exposure of a zinc cell at the test site Birkenes in Southern Norway. This site has a large impact of long range transported sulphur pollutants, and the measurements have also been used to evaluate the question of possible corrosion effects from these pollutants on zinc. The cell has performed well for almost the whole measuring period, small shortcircuiting periods may be excluded with negligible error. Analysis of the electrochemical and environmental data show significant corrosion effects on zinc from the precipitation as such and also indicate qualitatively short term corrosion effects from rural levels of sulphur pollutants. The study has shown that the electrochemical technique is a promising method for providing informations about short term variation of the corrosion rate and time of wetness under various environmental conditions.
