I USED to know a thing or two about solid state chemistry, but ceramics were never my main thing. I have, however, never heard of metals used in ceramics causing bimetallic corrosion. Such ceramics are used often enough as bearings (not, notably in any 747 of TWA800's vintage) to make such problems widely known if they exist.

The only things I can find on the topic indicate use of cermaic call bearings helps with corrosion control.

The titanium and aluminum would cause the bimetallic corrosion in the expanding rod warhead.

The rod joints are made of the same metal as the rest of the rod.
