The effects of chemical additives on the hydrogen uptake behavior of Ti-6AI-4V alloy

摘要

Inorganic additives, Na(2)S(.)9H(2)O, Na(2)MoO(4)(.)2H(2)O, Na(2)CrO(4)(.)4H(2)O, Na(2)S(2)O(3)(.)5H(2)O, MgSO(4)(.)7H(2)O and V2O5 were added in 1 N aqueous sulfuric acid solution to see the effects on the electrolytic hydrogenation of Ti-6Al-4V (Ti-64) alloy under various operating parameters. Characterization of their behavior was realized by the employment of glow discharge optical spectrometry (GDOS), X-ray diffractometry (XRD) and potential monitoring. Categorization of these chemical additives according to their hydrogen uptake behavior and comparison of the results for Ti-6Al-4V alloy with those for ferrous alloys were also performed.
