Effect of Phosphonium-based Ionic Liquids on the Corrosion of Carbon Steel under Gamma Radiation

Abstract

The interactions of two ionic liquids with carbon steel surfaces were studied in absence and presence of γ-radiation. Both studied ionic liquids were found to corrode the carbon steel. One of the ionic liquids (labelled [P₆₆₆₁₄]⁺ [Br]^-) was found to produce corrosion products both with and without radiation present. The second ionic liquid (labelled [P₆₆₆₁₄]⁺ [NTf₂]^-) did not corrode the steel in absence of γ-radiation, but did corrode it in the presence of γ-radiation.
