[QUOTE="Dzaw, post: 144860, member: 7794"] Absoloutly true, they aren't as critical. However, nitriding should make the part stronger, and odes not impact the toughness of the substrate, thus the safety concern is at least a null factor. As far as accuracy, that's why I prefer the plasma / ion process over gas or salt bath nitriding. With the other two you get a nitrided case, and a "white layer" of pure nitrides on top of that, changing the final dimension by the thickness of the "white layer". Further, the other processes can roughen the surface, wheras plasma nitriding can be set up not to do so. Not that I would trust the service to leave a perfect finish, I, personally, would suggest re-lapping after nitriding. This has the advantage of polishing up that nice, ultra resistant nitride layer, but the stuff is quite hard, so you won't change the dimensions an appreciable amount either. When you say there are "that many" nitriding processes, exactly what do you mean? I am not talking about PVD coating with titanium nitride, but rather infusing the case of the substrate with the nitrogen atoms in an ionized plasma. The PVD coating technology has a great deal of promise as well, but I don't think it's ready for gun barrels yet. [/QUOTE]
