Abstract
The anodic dissolution of tungsten has been investigated over the pH range 9–14. The current-potential curves show a Tafel region followed by a limiting current which is stirring dependent. The results have been interpreted as due to the formation of a WO 3 or hydrated WO 3 layer on the electrode surface which can reversibly dissolve in the electrolyte leading to a dependence of the current on diffusion layer thickness. Impedance measurements show only a charge transfer resistance in parallel with a double layer capacity (with a Warburg impedance additionally present in the region of limiting current).
