Abstract

Commercially pure titanium and a Ti-6Al-4V alloy covered with a thin thermal oxide film derived from hot rolling were electrolytically hydrogenated in 1N aqueous sulfuric acid solution (H₂SO_4(aq)) to see the influence of thiourea (H₂N-CS-NH₂) on the hydrogen uptake of both metals under atmospheric conditions. The inhibitive effect of thiourea was evaluated through quantitative composition analyses (by using a glow discharge spectrometer, GDS) and qualitative microstructural examinations (by using XRD). Thiourea acts as a hydrogenation inhibitor irrespective of the applied current densities. However, the inhibitive effect is more evident at lower charging current densities for longer operating periods.
