Effect of dissolved Si on the corrosion of iron in deaerated and slightly alkaline solutions (pH ≈ 8.1) at 50 °C
Source abstract
Abstract
Corrosion of iron in deaerated and slightly alkaline buffered solutions was investigated for different Si concentrations ([Si] varying from 0 to 110 mg L-1) over a 30 days period. In this environment, iron corrosion led to the formation of a layer consisting of a mixture of Fe oxides and Fe silicates on the metal surface, but also to the precipitation of the same compounds in the medium and to the release of Fe cations. An increase in [Si] promoted the formation of Fe silicates at the expense of Fe oxides, but without causing an enhancement of iron corrosion.
