Hs. Kuo et Jk. Wu, PASSIVATION TREATMENT FOR INHIBITION OF HYDROGEN ABSORPTION IN CHROMIUM-PLATED STEEL, Journal of Materials Science, 31(22), 1996, pp. 6095-6098
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.
