From the Dec. 14, 2010, Scientific American.

Tiny, iron-eating bacteria are proceeding to finish off the great ship.  Scientists analyzing the ship discovered a new microbe that eats iron.

The ship is covered with rusticles, icicle-shaped accretions of iron oxide, otherwise known as rust.

Some estimates put the Titanic's end in as little as twenty years.
