Keep in mind that hydrogen (or in this case deuterium) in
such metals is extremely mobile.  Consequences include:
 -- The formula TiDx, should not be interpreted as
    indicating that a chemical compound exists.
 -- If you apply an electric field, there will be a flow
    and/or concentration gradient of H/D atoms.
 -- If you're not careful, the atoms will electromigrate right
    out the end of your sample and into your hookup wires,
    if they haven't already.  This depends on what the
    wires are made of, and depends on the effectiveness
    of whatever barrier layers you've arranged.

I assume the point of the exercise is to set up a barrier
that doesn't conduct H or D, so that there accumulates an
elevated concentration there.  The electric field is what
matters;  the flow of electrons is mostly a nuisance effect
in this scenario.

There's got to be a ton of literature on this.  It's been
part of the cold fusion scene since the first Pons and
Fleishmann "results" in 1989.  And the general topic of
electromigration was part of legitimate physics and
chemistry for decades before that.
