Abstract

Based on the the practical engineering problem about the rapid failure of AZ31B magnesium (Mg) alloy anodes that have removed planktonic SRP after sterilisation in oil pipelines applied to beach environments, the corrosion damage of AZ31B Mg alloy by organic metabolites including mannose, glucuronic acid and glucose produced by a sulfate-reducing prokaryote in seawater was analysed using weight loss measurement, electrochemical tests and surface analysis techniques. It was found that the corrosion of the Mg alloy anode matrix was accelerated in the presence of organic metabolites and there were more corrosion products on the surface of Mg alloy, which provided theoretical support for extending the life of Mg alloy anodes in oil pipelines.
