Abstract
Anodic polarization of tungsten in WO3-NH4OH-H2O electrolytes has been studied. The effect of WO3 concentration (from 25 to 100 g/l), NH4OH concentration (from 100 to 250 g/l), and temperature (from 20 to 50 de grees C) on anodic current density has been determined more accurately than earlier by measuring the potentiodynamic polarization curves at different anodic potentials. The dissolution activation energy in the active dissolution range of tungsten has been determined
