Titanium Aluminum Nitride Finish

Gentlemen, I'm starting to canvass people's interest in a Titanium Aluminum Nitride finishes on their M1911s. I have established a relationship with a company that is very experienced in chemical and physical vapor deposition.

The coating is TiAlN over steel. The result is a phenomenally hard, wear resistant coating. The micro pores also act as a trap for oils so it technically is considered 'self lubricating' as the silicon in the oils will remain in the small voids. Awesome.

The thickness of the vapor coating is only 5 microns (5X10^-6 meters) so the roll pins will fit with no worries.

The result? The most durable, most corrosion resistant finish on the market.

The color is a somewhat medium gray. It can be polished to a mirror finish or be left as is. There are other options here as well. I was told of a Titanium Carbonitride that has a slightly mauve color as well as Titanium Aluminum Nitride or Titanium Nitride that is black or "very dark gray" in color.

The entire frame was coated as was the slide and all internals and rollpins. So were the Novak sights.

Cost hasn't yet been established, but we're about to establish this very soon. I do know that the price will be a function of throughput volume (monthly basis). I have to further discuss turnaround time (which is also a factor in determining the cost).

I do have photos of my Springfield Armory TRP [customized by Marianne Carniak of The Accurizer Gun Shop; Troy, MI (248) 528-1552], but I need a host site to place the photos. As soon as I find one I'll post the pictures.

Those who are seriously potentially interested (or just plain curious) please feel free to contact me via PM, e-mail or phone:

I would like to see the finish a little darker personally. Although if it is as durable as you say I could live with the gray color. I would like to see how it looks on a polished gun.

I agree with you that I'd prefer it to be darker. I will be having this discussion Monday of next week. I was told that the coating can be polished to a "near mirror finish". I imagine some highlighting along the slide would be nice with a dull matt finish on the top of the slide. I'd also like to see the sides of the hammer highly polished.

That said, if it TRULY lives up to the claims (and I don't doubt it) and the surface is properly prepped then it should not flake off. I'll be trying to wear this finish with several classes and daily carry/drawing, etc. I could live with the gray, just as you've stated, but only if it performs as claimed. However, black Ti coatings exist as well and I'll inquire about them.

I've taken the firing pin (also TiAlN-coated) and we've been trying to remove the coating with no apparent wear on the finish. We've cut it in half and will drop one in a saline solution.

I'll keep in touch.

Thanks for you patience.

TiN Options

Ive just spoken with the owner and he states that he has several finishes that can vary in color from lavender to bright gold.

I informed him that the majority will prefer "dark charcoal" to "preferably black".

He's checking his processes and "doing the numbers".

Titanium Aluminum Nitride Coating... Color is DARK CHARCOAL

I picked up the TRP today. The color is ACTUALLY dark charcoal in color. :lol: There isn't much difference between the color of the sights and the color of the pistol. It's absolutely gorgeous. I was ecstatic when I looked at it because I was expecting a "concrete gray" with a greenish tint. Nope! Not at all.

I'll be taking photos and posting them -- hopefully this weekend.

I've been playing phone tag with the owner trying to discuss cost. I imagine he's been trying to figure out why it came out gray as opposed to charcoal (due to the funny lighting for the photos, apparently).

I'll get the necessary information ASAP.

Springfield TRP with TiAlN Finish -- Update





These photos are correct in that the colors are accurately presented.

Things of note:

The initial slide to frame feel when working the slide is just a bit "gritty". Not especially so, but it's initially not as smooth as, say, my Wilson CQB. What is the root cause? I find the finish is ever so slightly coarse which is great for gripping the slide to rack it. Does it impede performance? No, not at all. I much prefer the surface finish (which is very matt, btw) to, say, Roguard which has a surface finish that is much more reflective and slippery.

Wear: After drawing it in and out of a kydex holster there is no observable wear. I'm now having difficulty keeping motivated to continue the '500 times a day' drawing and reinserting, but I labor on. How long will I continue this? I don't know. Maybe a month.

Dissassembling the pistol does not in anyway reflect a poor quality job at all. The roll pins fit just fine and all crevices that I can determine are coated.

The finish does seem to maintain a fine coat of oil. However, when I carry I carry in leather and when I remove the pistol it appears to be bone dry on the outside surface. However, under bright light and a fine white cloth will reveal that there IS lubrication -- I assume in the micropores.

After firing one notices a transition of material from the brass on the slide ejection port similar to what one finds on a Glock pistol. Also, by rubbing any other metal on the surface also yields similar results.

Thus far I'm very, very pleased. Particularly that the color is "dark charcoal" or "graphite" and very pleasing and the surface finish is suitably rough that one can quickly obtain a grip on the slide -- even if it's less than ideal contact.

Has anyone had any experience with BodyCote's finishes:

Tungsten DLC (Diamond-like Carbon)
Boron Carbide


I'm particularly curious how well BodyCote's finishes adhered to the surfaces of the substrate materials and how rough or smooth were the surfaces prior to applying it.

Obviously, the rougher the surface the greater surface area and while the mechanism(s) are complex and involve much more than surface area (there is surface transition) it should assist.
