n = near near Diamond Like Coating.

Sorry. I may not know what the "n" stands for, but I do know that DLC means "Diamond Like Carbon," not "Diamond Like Coating."

https://en.wikipedia.org/wiki/Diamond-like_carbon

"Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from some of those properties.[1]"

"For example, a coating of only 2 ÎĽm thickness of ta-C increases the resistance of common (i.e., type 304) stainless steel against abrasive wear; changing its lifetime in such service from one week to 85 years."

"This means that one-ÎĽm thickness (that is ~5% of the thickness of a human hair-end) would increase service lifetime for the article it coated from a week to over a year and two-ÎĽm thickness would increase it from a week to 85 years. These are measured values; though in the case of the 2 ÎĽm coating the lifetime was extrapolated from the last time the sample was evaluated until the testing apparatus itself wore out."

I think the NDLC store sent Glock drums of Rustoleum instead of NDLC for the barrel-coating.

Fair enough, I was only going off this definition,

DLC Coating stands for diamond-like carbon coating, and is a nanocomposite coating that has unique properties of natural diamond low friction, high hardness, and high corrosion resistance.

I'm not a chemist or a scientist, that was as close as my pea sized brain could come up with this late at night...:)

I know more about the polymer comps....I don't do finishes....

Thinking about it a little more, its likely the n stands for nano.

Is it just Glocks version of DLC. Or trademark. Kind of like melonite vs tennifer. All I know is it’s a super tough surface. Even when the black wears away it’s impregnated into the surface of the metal. Well I’m no scientist but that’s what I have read. For some reason my post on the triggers I had coated disappeared on GT. I put 400 rounds through the 19 Gen5 and no discernible wear. I’ll put another 400 in today. Probably see how it looks after around 1200 rounds. Mix of +P Hornady and WWB 115 grain. Seems to be holding up well. Sorry don’t have a trigger gauge to measure weight. Doesn’t seem lighter than a factory trigger but smoother. Maybe it’s all in my head? It has seemed to have broken in a bit. If you look on the barrels of a well used Gen5 barrel it shows wear but I think the coating/surface treatment is still there.
Update!
1300 Rounds. So to the naysayers this is a viable coating for the connector and trigger bar. It will extend service life in extreme conditions or lack of lubrication. It’s superior to Glocks standard trigger/connector coating.

After 800 rounds! 400 more to go and not one sign of de lamination or chipping.

Good to know, thanks.
 
Maybe if we post enough in here Glock will see that this is a feature we want and start putting DLC coated internals in the Gen5. It would cost them probably $1 more per pistol to do it. They already do it for the M. The fixed they frame bevel after seeing that that’s what the customer wanted.
 
It could just be a marketing term, either from Glock or from the company applying the coating.

If it refers to a physical characteristic of the coating, I'd guess that it refers to one of three things: orbital arrangement, nitrogen doping, or deposition method.

Regarding orbital arrangement, I've seen "g-DLC" used as a reference for hydrogen-free DLC with specific sp bonding.

I've seen tungsten doped DLC written as DLC:W, W-DLC, W DLC, and even wDLC, so perhaps nDLC is nitrgen doped DLC. If this is the case, I’d imagine it’s a combination of chromium, carbon, and nitrogen, and they’re highlighting the nitrogen part (CrCN).

Lastly, perhaps the small n refers to the deposition method. DLC is often applied by physicals vapor (PVD), but maybe they're using some other method and they're highlighting the size (nano). Though, if the “n” does stand for nano, it would really just be a marketing term, as all DLC coatings are deposited at the atomic level whose resulting thickness are measuring in microns.

They're supposedly doing it in-house. ^ Thanks, have known of some of the application methods, just never heard of 'n'. You make sense.
 
Marketing, since the metal underneath was already Nitrided -- just to appease all the future complainers about the "frying pan" finish, and how one Glock "finish" seemed better than the other.

Wait for the first complainer about how their finish got scratched, or barrel shows rub marks.
 
It had nothing to do with marketing and everything to do with the FBI contract bid. When the Govt asks for something in a submission you give them what they want. The Gen5 is basically the M. What your saying cciman is pure speculation. It’s not based on and proof or facts.
