Hmm...the book by Eckhardt Schmidt, Hydrazine and Its Derivatives has a wealth of compatibility information. You need to be more specific about what you mean, do you care about effects of the materials on hydrazine, or the other way, or both?
Silver in general is mildly catalytic towards hydrazine, but hydrazine won't really do any damage to the silver (it actually would remove tarnish and brighten it a bit). I don't think TiN coatings would react (it's pretty inert stuff, and is attacked by acids not bases = hydrazine), but not sure where to tell you to look for data, not sure if it is in the book or not.
