Dez...what are you using the Ti bolts for, and what alloy are they?
Ti bolts, size for size, are weaker than steel bolts, though there are a few expensive alloys that are comparable.
Try it out sometime...grip the hex of a small bolt in a vise, stack washers up to the threads, then torque a nut on there until it shears the bolt and observe torque value.
Once you get the shear torque for a Ti bolt, try it with an identically sized steel bolt (OEM bolts, not cheap Ace hardware crap) and see what you come up with.
A deflection beam torque wrench is a great way to measure shear torque, and if you have a torque wrench that records max torque, even better.
What you're doing is getting an idea of the difference in strength between Ti and steel to see if the Ti you have is strong enough as a replacement.
Maybe throw in a SS bolt too, just to see where they stand in the scheme of things.
No special treatment is needed for Ti, it's naturally corrosion resistant, and in most cases even more resistant than SS.
It's why you hear of so many people with Ti pins and rods in broken bones, because it won't break down in the corrosive environment of oxygenated blood, salt, acids, electrolytes, water, and all sorts of generally bad things to leave metals in contact with.
The only time you have problems with Ti is when it's heated past 800-1,000F, then it starts oxidizing.
You still have the same problem with galling as SS, since it's a non-ferrous metal, so you have to take the same precautions.
