Hydrogen Concentration Measurements at Titanium Layers by Means of Thermo-EMF

Article Preview

Abstract:

The thermo-emf and electrical resistivity of hydrogenated titanium were measured. Hydrogen concentration in titanium varies from 0.005 to 0.25%. We have compared the methods regarding their sensitivity to the alteration of thermo-emf and electrical resistivity during titanium hydrogenation. The accuracy of the obtained results was verified by comparing them with the results for palladium. It was demonstrated that the method implementing thermo-emf is sensitive to hydrogen concentration in titanium at different depth of the alloy. On the basis of performed measurements, we have proposed a graphical method for detecting the change in titanium structure.
