Nobility of W and Ti

I have a small question:

I know the standard electrode potentials of reduction for Ti3+ and Ti2+ to Ti-metal, which is surprisingly low (lower than Zinc even!). But i can't find the same values for the same process with tungsten (W).

Which metal is most "noble" of W and Ti?

The reason i wonder this is because i was discussing with a friend who has a ring alloyed with both metals, and he claims that titanium is more noble. Ti resists corrosion because of a passive layer of Titanium oxide, similar to aluminium, but in terms of reduction potential, titanium is very "un-noble". If it wasn't for that oxide layer, titanium would corrode very quickly in normal conditions.

My intuition tells me W should be more noble (chemically, as in less electropositive, higher reduction potential in formation of metal), does anyone here know for sure?
