Nitride Treated Barrels?

[Mjolnir]

"If it out lasts chrome lining I am for it maybe because it is new in the states I cant find much info as to barrel life. Is this treatment similar to melonite treatment? I can remember Grant posting that it did not have the best results in a .223 bore?"

People use improper vernacular. There is Titanium Aluminum NITRIDE, Titanium NITRIDE and other nitrides that are physical vapor deposition COATINGS. Then there is Ferritic or Salt Bath Nitrocarburization. There is the caustic salt bath and Ammonia "vapor" (not really) type. The Salt Bath appears to be better of the two - at least for automotive valves.

So one must ferret out what exactly do they mean when someone states that "thus and so is 'nitrided'".
