Abstract
Hydrogen permeation transients for passivated chromium-plated steels w ere measured at room temperature as a function of cathodic charging cu rrent density. The passivated film on chromium plating is shown to be an effective barrier to hydrogen at low cathodic charging current dens ity (40 and 100 mu A cm(-2)). The passivated film can be reduced to ch romium at higher cathodic charging current density (1 and 10 mAcm(-2)) , promoting hydrogen absorption significantly.
