By this logic, since a _bow_ is listed as doing 1d6/1d8 damage, I could make an adamantine bow and it would get a natural enhancement bonus.
Yes, if your DM is a dolt (or into really high powered magic) and allows adamantine to replace wood components. That is the same DM that allows greatswords to be made out of water or sand.

Chapter and verse, please.
So you are arguing what? That an adamantine battleaxe is not made entirely of adamantine?
"This non-magical axe is made out of adamantine..." pg. 188 DMG
"This non-magical breastplate is made out of adamantine..." pg. 182
"This large non-magical shield is made from adamantine..." pg. 183
"Weapons fashioned from adamantine..." pg. 242
Notice how it does not say that the battleaxe, breastplate or shield are made out of hog's droppings, steel, wood, leather, and adamantine.
By your rationale, one could make an adamantine battleaxe by just lining the blade with adamantine, since all that matters is cutting area. However, notice that the book does not support your view. It does not say, "only the cutting edge or impact surface of a weapon need to be made of adamantine."
It does say, however,
"...this ultrahard metal adds to the quality of the weapon or suit of armor based on how much of the material is used." pg. 242
And...
"Adamantine has a hardness of 20 and 40 hit points per inch of thickness."
Ruling that adamantine works the way you say it does opens a whole new can of worms:
Do composite adamantine/wood weapons such as a battleaxe gain the hardness and hit points of adamantine or wood? If you say both, which part do I sunder? Can I make a battleaxe completely out of adamantine? If so, how much would it cost? Why is it that an arrowhead gains more of a bonus from adamantine than a dagger, even though a dagger uses more adamantine?
.

And if all of the above doesn't sway you, I guess it might be necessary to whip out Rule -1.
