Abstract

Corrosion behavior and pitting potential for Fe in aqueous fluoride solutions were investigated by potentiodynamic and potentiostatic polarization measurements. It was found that the solution pH and total fluoride concentration, [F]total affect the pitting potential which moves to more noble direction with decreasing [F]total and increasing pH values. Furthermore, it was found that the chemical morphology of fluoride in solution affects the corrosion behavior of Fe. Uniform dissolution is observed in HF, active state pits occur in HF+F- and polishing state pits occur in F-.
