I've been thinking about getting my bolt assembly and carrier group coated in 1 micron of titanium nitride. Has anyone had this service done and where did you do it? Is this a complete waste of money? Opinions?
 
First I think it should be done on a brand new bolt carrier .. I worked a lot with tool coated with TIn on carbide tool, an for sure it make the tool to wear a lot slower less friction.. I experience this more on aluminium part. The metal part... there other coating that perform more on SS or hardened material but for ALU type I would try...
I dont know if the cost would be ok
 
Would advise you to check more closely into it as there are many kinds of "TiN" like coatings and some have to be applied at higher
temperatures which could affect heat treatment. Just something to consider before diving into it.
 
good to know... I know how it's good on tool but I know nothing the way to apply it on gun part.... I just end up with JP BCG in FMOS...it like on ball bearing BCG so im not missing the TIN thing :p
 
Why? Do you fire 10,000 rounds a month? You'd shoot out your barrel long before you'd wear out your bolt from the abrasion that TiN would protect against .

Leave TiN coating to machine tools. I cannot express in words how much of a waste of money this would be.
 
thats why..me, I end up with QPQ stainless FMOS BCG from JP.... problem solve..but TIN was something I was curious at first!!
 
New technology allows Physical Vapor Deposition (PVD) coating to be deposited at temperatures as low as 390°F (normally 750°F to 930°F) without compromising either the properties of the coating or the substrate. However, unless your part is a consumable and the added cost of coating is offset by the gain in life vs. replacement cost, it is financially inadvisable to get the coating. However, TiN and other PVD coatings are pretty and add both aesthetic and functional benefits to the object they are applied to. One of the major reasons why TiN is selected for a coating is because it is gold colored, and shiny gold things sell better than shiny not-gold things.

A really nice graph showing both the hardness and approximate color of various metals and coatings:

Do you plan on drilling holes with your TiNi bolt?
Cerakote is another alternative.
I've got some space shuttle tiles if you want to try those... Excellent thermal resistance!
