Abstract

The anodic behavior of tungsten in water-amino alcohol solutions of sodium chloride is studied potentiostatically and potentiodynamically on a rotating disk electrode. The introduction of monoethanol amine (MEA) into an aqueous NaCl solution leads to anodic activation of tungsten. From the dependence of the current density on the disk electrode rotation rate, it is determined that the anodic dissolution obeys the diffusion kinetics equations. The delivery of MEA molecules to the electrode is the slow stage of the reaction. The dissolution rate and the tungsten surface quality after the treatment are the highest at 6 M MEA. The effect of physicochemical properties of solutions on the anodic reaction is shown
