would this be a good idea for a barrel (chemical coating)

Diamond-Like Carbon (DLC)

thickness of coating would be .001 to .005mm with added smoothness and lower coefficient of friction...

Not sure about this one. You'll be changing the dimensions of the lands and grooves, but this is a bit outside of my zone so I don't know if .005mm is significant (my gut feeling says it is, though). Also for the FX smooth twist barrels, you might be turning them into a smooth bore if you line the inside.

If my arithmetic is correct, the thickness would be less than .0001", so my guess, thickness alone would not be a problem, as most manufacturing tolerances are not that exact. I'm thinking here of traditional cut, button rifled, and hammer forged barrels. The FX barrels and liners might be a different matter. You could inquire of some barrel makers, but I'm pretty sure none will recommend it. I believe you would just need to experiment with it, at the risk of needing to replace a barrel. My guess, it is not going to improve a good barrel, nor fix a bad barrel, so I would spend the money on some good bourbon or pellets. One thing is certain, you'll never screw up a barrel by leaving it alone.

If I had the ability to access that technology at minimal, or no cost, I'd be all over it. Who knows what you may discover that others say won't/can't/shouldn't work. My guess s over 50% of us on this forum tinker to our own ability level. Dreaming and problem solving is what keeps us going.

Hell, half the fun of this forum to me is seeing what others have dreamed up, created, and have the ability to do.

Keep thinking outside the box.

FYI: They have been hardening crankshafts by nitriding for a long time.

The only application of DLC I'm familiar with is in motorcycle suspension. It reduces friction by a lot but have only seen it used on the outside of the steel lower slider of the forks.

i was thinking reduction of friction = good, less wear and less need to clean the barrel... but it would slightly change the dimension of the diameter. has this been done before?

Thickness wise.0002" max, thickness, should not be a problem.

My biggest concern...is could it be deposited "properly" (read that evenly) into a piece of small diameter tubing of .177" / .22" / .30" diameter.

Plus as with most coatings, there is more deposit on hard corners that on smooth surfaces. So there may be a buildup of material on the corners.

Less pellet friction, sure, lasting longer, sure, but again, can it be applied evenly into a "small" diameter ?

GREAT for trigger, and cocking parts. A perfect solution for rough trigger components. Same for the pellet probe (correct word ?).

Interesting... The Skout Epoch barrels are coated with Nickel Teflon in the bore...

The EPOCH®’s barrel liners have a low-friction nickel and PTFE impregnated finish which is designed to self-clean with the use of soft lead projectiles. Cleaning the barrel’s bore should only be performed in situations where dirt or other debris has made its way into the barrel.

Hmmm wonder if one can use DLC (like powder coating system ) on pellets ? but then there is the environmental issue too ? or is there ?
