I am strongly considering buying this which comes with titanium nitride coating.

Does anyone know about the Titanium Nitride in terms of durability, scratching, repairing or anything else that is good or bad about it.

Thanks.

Mike

Titanium Nitride (TiCN) is an extremely hard coating commonly applied to high speed and carbide cutting tools to improve cutting time. It's about .00004 thick and approximately 70 Rc and higher for hardness. The photo you have supplied is black and TiCN is typically gold in color, but I suspect it can be almost any color it wants to be.

I have no experience with it in firearms but would suspect it to be expremely good as a rust preventative and as a scratch resistant surface.

I have Titanium Nitride coated drill bits. They run cooler and lastlonger than the regular bits. I doubt if this applies to you, but the gold color makes them easier to find when you drop one on the floor litered with drill chips and other debris.

Is this the gold colour.

This is on a Wby 460 done as an Accumark on gunbroker and claims to be Titanium Nitride

I really doubt that is Titanium Nitride. It does not look right, nor does the giant scratch down the barrel indicate to me that it is coated in something that is much harder than steel. I would stay away.

The only titanium nitride gun part I have any experience with is a bolt carrier in an AR-15 that my friend has. He has never shot it, so I can not comment, but it is a gold color. I have never seen it in any other color other than a bright gold.

TiN (Titinanum Nitride), TiC (Tititanum Carbide), TiCN (Titinanum Carbo-Nitride) all have different colors, and slightly different wear properties.
You can find some of the material property differances at www.ionbond.com, even though this is a "cosmetic" appliciation.

Hello,
Dealer friend of mine just returned from distributor show and Remington had a rifle supposedly coated both inside and out with titanium nitride and anyone there could take a washer or coin and attempt to scratch or mar the surface, but to no avail. Will be interesting to see and they call it the indestructable rifle. Just turn it over to a bunch of marines and we will see how indestructable it is??

Judging by color, it is more likely TAlN. Nesika and Borden have been offering TAlN coated rifles for awhile now.

Been using a few TAIN (Titanium Aluminum Nitride) coated tools at the shop. Different brands of carbide seem to have a different shade of black for the color. Some have almost a tinge of purple to them.

TICN is always a purple color and adds greater durability than TIN, which is gold in color to cutting tools. TAIN is one of the newer coatings that we've been using with exceptional results with stainless.

The problem with any of those coatings are the weakness of the base material under them, which is why you don't see nearly the improvement in tool life between coated or uncoated high speed steel as you do with coated or uncoated carbide cutting tools. The more dense the base material, the more effective the coating is. If the base material can move or flex, the coating will breakdown quickly, or flake off.

Unless the parts that were being coated were of high heat treat properties, it would be unlikely that this coating would hold up very well, but without some more thorough testing, it's kinda hard to tell.

Triggers, sears, and cocking pieces are prime canidates for such a coating, but anything that's not extremely hard, as in heat treated, would most likely not be that great.

Matt,

Would consider that finish Weatherby is using to be inferior to matte bluing.

I don't know for sure what Weatherby is using for their finish, but if it is infact a TIN coating, it would be more durable than matte blueing, even though the material is not as hard as it should be.

The part I'd have a hard time with is the fact that you'd end up with a gun that "Gold Finger" might take out hunting.

If anyone is going to build a pimp gun, it would definately be Weatherby

As Matt said, some of these coatings are really getting popular in metal cutting tools. Now, the uses for the coatings there are different than what we are looking for in a coating for guns. One of the primary advantages on cutting tools is added lubricity, more or less cutting down on friction which builds up heat and breaks a tool down quicker. Abrasion reduction also plays a role. A coating for guns needs to repel scratches and damage, but it's main purpose is rust protecion. You don't want anything that might allow rust underneath the coating. I'm not sure if anyone has tested how these coatings designed specifically for cutting tools would handle environmental rust tests, or the thermal and mechanical expansion a gun barrel goes through during a typical bench session.

When I worked out East building Titanium Mausers we sent them out to be coated with a black coating used for milling cutters. I'm not sure exactly what it was, but I remember it was advertised at 90 rockwell on the C scale. We tried this to make the sticky Titanium a little smoother. It worked ok, but it didn't have the same coefficient of friction as case hardened steel, and wasn't as glass smooth as the old 98 military version. I guess the hardness of the coating really has nothing to do with how smooth it functions it's the coefficient of friction on the surface that really matters. I think the cost of coating a barreled action & related parts was over $500.

Check into Melonite. Been around for a while, It penetrates the material and brings out a matte black color. The first co to use it was America Arms&Ordnance (Charles Poff), more recently Beretta, Sig and S&W have used it. It gets away from the issues Matt Williams raised.

IMHO,
tin would be GREAT on a bolt, for a slick, harder than rec surface... no galling, less stickiness...

overall? Might be an option to teflon it after, though a matte tan (if darker would better) is about invisible in the field (looks like sun on a limb)

Are you saying that is why the Wby I illustrated in my opening post is black.

My main concern is not advantages it might provide but rather disadvantages it might provide.

Mike

Not sure of what Wby used, but the few rifles I have that are Melonited are black and the surface will not come off unless you machine it. I would use that more so that TIN etc

John

I've seen custom sears and hammers for 1911 pistols that were TIN coated. They're in the Brownells catalog.

TIN is undoubetdly a very durable coating and makes excellent drill and milling bits, but the first question I find myself asking is how is it at holding up agains H2o?

I could possibly find a couple of parts to put it to use on, but for the most part Im in agreement with Paul H. A bit too "glittery" for practial uses.
