View Full Version : LaRue's ION bonded Barrels

Looking at LaRue's Stealth uppers, here is a quote regarding their barrels:

Unless you request bead-blasted stainless, our barrels arrive ION Bonded in black. Ion Bond coating is roughly 5-millionths of an inch thick and roughly 90 Rockwell in hardness (harder than hard-chrome). It won't chip, peel, corrode, and is heat-resistant to over 1200 degrees Fahrenheit.

Can anyone speak to the ION bonding that LaRue utilizes, and how it compares to chrome lined barrels? The quote indicates that it is "harder than hard-chrome", but I'm not really sure how to quanitfy that -- how much harder, and how does that relate to real world applications?

ION bond is external only, so it behaves exactly like a stainless barrel internally.

Yeah, what he said. The ION-bonding process is simply to color the barrel black, so it's not shiny stainless.

The bore of the barrel is just shiny stainless, which is ideal for accuracy.

That's not the point of a Larue barrel though. The point of a Larue barrel is accuracy. That's why the bore is NOT coated/treated/plated/bonded in any way.

Tonka tuff is good for bore life, but not accuracy.

That's only because most bore coatings are highly imperfect.

If you did a layer-by-layer or a good deposition technique, you could not disrupt the surface and thus maintain accuracy.

Coated bores are generally not as accurate as non coated because getting a coated barrel to shoot well required more prep/machine time which costs money.
While chrome and others coating are not usually made for accuracy they can can be very accurate. All depends on how much money you or the producer wants to spend.

Most shooters shooting their typical ammo will never see the difference in accuracy between quality chrome-lined and stainless barrels.

http://forum.m1911.org/showthread.php?t=41517&page=2&pp=10

Quoting John Harrison regarding Ionbonding my old 1911:

"Hi,

The name of the company is IonBond, LLC in Greensboro, NC. The finish is called "DLC" in the firearms industry. It's hard to accurately do an apples to apples comparison of the finishes, since they are apples, oranges, bananas and grapefruits, but here's my short $0.02 worth.

Bear Coat and Black-T are sorta cousins in that they are sprayed on coatings that are baked at a fairly low temp to cure. So long as their skin is not broken, they have the highest advertised salt spray corrosion test numbers, like a 1,000 hours or such.

Neither Bear Coat or Black-T is particularly resistant to abrasion, when compared to Melonite and DLC, although they are more durable than bluing and Parkerizing, maybe because the coating thickness is greater. Folks will argue that one is appreciably more durable than the other but I just can't see a huge difference myself. My own experience with using Black-T on a bunch of pistols and Bear Coat on a few is the chief difference to me is that often times the Bear Coat was so thick as to require a bit of controlled sanding in concealed places to get the parts back together after being finished in Bear Coat. I've never had an assembly problem with Black-T, even on fairly tight guns.

Melonite and DLC are a more fair comparison to each other as both are really hard on the Rockwell "C" scale. DLC is advertised at 70 to 90. I don't know about Melonite, but would expect a similar test result. Melonite is a surface treatment that is finished off in Black Oxide (think bluing) where DLC is a PVD (physical vapor deposition) coating. From my experience, the black color is more durable on DLC. To me, the big difference between these two is the temperatures involved. Melonite is done at temps around 1200 degrees, give or take; where DLC is done at 400 degrees (just a little hotter than bluing tanks). Aside from the obvious difference in temperatures that the gun is subjected to, this means is that the smaller parts like extractor, pins, screws, sear, hammer, magazine catch, etc. cannot be finished in Melonite. They have to be finished in black oxide or a spray on finish. With DLC, all the parts can be done.

DLC's salt spray test time is claimed at 48 hours. Bluing fails in under 3 hours normally. I don't know what Melonite is rated at.

I did have a lot of problems reassembling pistols treated with Melonite, mostly having to lap fit the slide & frame rails after the treatment. I've had no problems with DLC with reassembly.

Melonite seems to only be available in matte finishes, where DLC can be done on polished surfaces and in my eyes, looks so much like bluing that you can hardly tell.

Hope this answers some of your questions."

I believe the LWRC "NiCorr" surface is the same way.


NiCorr is closer to Tenifer and Melonite...

Ionbond DLC is a PVD coating that uses a layer of Hard Chrome to attach the "Diamond Like Carbon" too

http://www.ionbond.com/dynasite.cfm?dsmid=83917

PVD TECHNOLOGY

Physical Vapor Deposition (PVD) is characterized by the creation of a metal vapor that can be reacted with different gases to form a thin film coating. The most common PVD methods used today are arc deposition and sputtering. Both processes are carried out under high vacuum conditions within a coating chamber.

Ionbond introduced cathodic arc PVD coating technology from the former Soviet Union in the late 1970s and today the vast majority of tools are coated using arc deposition technology.

Process Temperature
The typical process temperature for PVD coatings is between 250() C and 450() C, however in some cases PVD coatings can be deposited at temperatures below 70() C or up to 600() C, depending on the application or coating.

Items Typically Coated
The PVD process is capable of depositing coatings on a very large range of tools and components. Applications include cutting and forming tools, wear components, medical devices and decorative products.

Substrate materials range from steels and carbides to pre-plated plastics.

Coatings Typically Deposited
The coatings typically deposited are TiN, AlTiN, TiAlN, CrN, CrCN, TiCN and ZrN. More complex coatings can include TiAlCrYN or a W-C:H / DLC combination.

The coatings can be deposited as mono-layers, multi-layers, graded layers and the coating structures can be modified in terms of such properties as crystallographic orientation and nano-composite structure in order to produce the desired properties in terms of harness, elasticity, adhesion etc. The final coating choice is determined by the demands of the application.

Coating thicknesses typically range from 2 to 5 microns, but in some cases coatings can be as thin as a half micron or as thick as 15 or more microns.

The cycle time is determined by the load density, coating type and thickness. Typical cycle times range from 3-6 hours.

Advantages of the process:

Flexibility in terms of substrate materials and coating materials / combinations
Short cycle times / high productivity
The low to moderate coating temperatures means parts maintain their geometry and tolerances
The process is environmentally friendly

Exactly, this is why Noveke makes MOA or better Chrome lined N4 barrels from FN M249 blanks.

You sure about that? My understanding is that Noveske does not actually use M249 blanks but uses the same spec of chrome lining (about twice as thick as typical M16 chrome lining). As I understand it, they do the chrome lining, bbl profiling, and chambers in-house. Not sure where they get the blanks though. Somebody please correct me if I am mistaken in this.

Trying to Source a Mid Length KAC URX with a flip up front sight gas block, or a Rifle URX with a hidden gas block...

AAC 52T Blackout Flash hider

Surefire Scout light

The usual TangoDown SCAR Panels and QD VFG

and of course...EOTech, this time I will go with a Model 555.
