Titanium Nitrate
I have been hearing about this lately but finally decided to look it up. What I have read is it is strong and looks good soooo, just for the heck of it I posted a URL to one of the posts on it.
https://en.wikipedia.org/wiki/Titanium_nitride
There is a book out with its name as part of the title but I haven't read it.

Re: Titanium Nitrate
You ever see those shiny gold colored drill bits? That's Ti nitride. (coating)
Been available a very long time, has many uses. It's very hard, as nitrides tend to be...
Titanium nitrate is something else entirely, and looks like not much use.

Re: Titanium Nitrate
I have some drill bits with the coating, I just never paid attention to what it was.
From what I have seen and heard that it is being used for coverage on a lot more things now days. I'm curious on just how it is applied.

Since I worked in detail part, assy and installation design and special protection was a necessity. Now retired and have no way of getting into what is going on and is it being used.

Re: Titanium Nitrate
I have drill bits and a couple of Pew Pews that have TiN coated barrels. I have one Drill bit that was about 25 bucks stand alone price. My choice of Pew PEW is a .45 and a Micro 9. Big and mini-me sized. TiN is some tough stuff. The Drill bit is a 9/16" with 3 flats to enhance grip and fit in a 1/2" drill motor. An odd bit to begin with.

Re: Titanium Nitrate
TiN is applied by chemical vapor deposition process. It’s a thin film coating technology. Been widely used for 40 or 50 years to harden things. Drills were an early application. You can’t do it at home, but services should be available in all areas. I don’t really know, but shouldn’t be crazy expensive.

"Automotive Components
The automotive industry benefits from titanium nitride (TiN) coatings on parts like gears, bearings, and engine components. These coatings reduce friction and wear, extending the life of these parts and improving vehicle performance and reliability. Titanium’s thermal stability is particularly advantageous in the high-temperature environments of automotive engines, enhancing efficiency and reducing maintenance costs."
"These coatings reduce friction and wear, extending the life of these parts and improving vehicle performance and reliability."
This is just one of the part that makes me uncomfortable. When torquing a bolt friction is important when holding the fastener in place. You tighten the bolt, stretching it, then friction snuggles in. The material mix in the bolt (shank and threads for example) change the strength of the bolt, e.g., torque rating. There are other things involved in the discussion such as "shear" but then does that get effected also by the Titanium Nitrate coating? I've sat at my desk (7 foot long) involved in discussions like this by engineers, material specialists, stress engineers and so on. Fastener design is not as uncomplicated as one might think.

Re: Titanium Nitrate
I don’t think fasteners are a common application, probably for the reasons you suggest. Application is mainly for wear parts. Cutting tools was an early and remains a common application. Drills, taps, dies, carbide inserts for lathe tooling, end mills. Most of us probably have some TiN coated tools now. Wear parts are also a common application.
This technology is very well developed, having been around for decades. There are other coatings applied via the same vacuum deposition method. Most of them enhance the wear characteristics of the part they are employed on.

Re: Titanium Nitrate
TiN is Titanium Nitrate.
When I was looking for something on -line I ran into pix of other things now being made using TiN coatings and they were not just tooling but parts for working things in other shapes and designs. I've worked on drawings of fasteners (for example) that either became MIL standards, NAS. ANSI or several other national standards or... stayed as company designs.
The design drawings were not just the drawings of the parts but included materials (also standards), mixing of the materials, forming, technical checking and so on all done to "standards". Designing and making parts are very complicated and more so when potential failure could be involved. Some of that potential failure is going on in the real world right now.

Some more information on TiN. Very interesting and there might be more uses. When I get time to "cruise" and seek more information.

Re: Titanium Nitrate
The gold coating is called Titanium Nitride. (Many, even most nitrides are hard. Think silicon nitride lifters...armor etc)
Titanium nitrate has no real industrial use, its not gold colored, and has its own wikipedia entry as it is NOT Ti Nitride.
Nitride !== nitrate. Different compound.
TiN does provide some corrosion protection and would largely prevent galling, so I could see it used on SS or Ti screws/nuts on some critical apps... Its probably cheap enough to replace Cad plating, might even work on aluminum. Most 300 series SS and anything Ti screwd together, loves to become one with the nuts or threaded bit, esp Ti.
Surprisingly TiN is reasonably conductive.
TiN can be CVD or PVD application, but the semiconductor grade ammonia and the cost of the vacuum pumps and required exhaust scrubbers, not to mention the equipment (surplus 50 year old barrel asher would work fine) and the RF generators you would probably want to use for PECVD are not cheap even broken...I suspect you could use N2 for the nitrogen source but I haven't noticed that in actual use for Making SiN... (Great name for a band)
Stopped and googled the CVD process, N2 IS used rather than ammonia, but the Ti carrying gas is TiCl4... the waste gas is mostly pure chlorine, so you get to buy scrubbers for that, and purge the chamber really well before opening it. PECVD would likely provide a denser film, and faster deposition rate.
Please don't try maikng Ti nitride in your garage, way to many chemicals with bad suffixes used . (...bromide or ...chloride as well as using ammonia for the N2 source as an option,)

Re: Titanium Nitrate
Thanks for the additional information Piledriver.
"Purdy" is not always a good thing but... it was interesting to look into.
The writings I posted also said not to do the TiN at home.
