Abstract
The effects of anions in saline solutions on the corrosion behaviour of magnesium alloy AZ31 were investigated using hydrogen evolution, pH and potentiodynamic measurements. The results demonstrated that adding bicarbonate and sulphate ions to saline solution accelerated the corrosion, whereas hydrogen phosphate and dihydrogen phosphate retarded the corrosion and decreased the open-circuit potentials. A model involving the magnesium hydroxide and magnesium carbonate film formation mechanism was proposed. The change in the solution pH over time did not reflect the corrosion rates of the magnesium alloys due to the influence of anions.
