Abstract

     An analysis method for investigation of H content in solids has been established based on hot extraction and gas chromatography system. This technique is used to determine quantitatively the amount of thermally desorbed hydrogen. The plating conditions (temperature of electrolyte, pulse parameters) upon chromium has a significant effect for the amount of hydrogen occluded in the electrodeposit.
