Phosphate vs nitride.

Easy cleaning is easy, mil-spec phosphate is the strongest finish by a country mile. I used to think in the mode of Paper vs 2 or 4 legged critters. Nitride lets you compete with the beauty queens, mil=spec phosphate has never been the reason someone didn't come home or not be able to chose: between the eyes or left/right pupil.NiB coated bolt carrier groups are in the middle range on price, more costly than black nitride or phosphate but far less than Titanium Nitride. Even though it is a popular choice, nickel boron can and does flake off from time to time so it is recommended to purchase a high end bolt carrier group from a manufacturer that warranties the coating ...The use of phosphate ion-imprinted polymers with AlGaN/GaN for phosphate ion detection have been also introduced by Jia et al. (2016). They functionalized AlGaN/GaN high electron mobility transistors (HEMTs) using phosphate anion-imprinted templates embedded in a polymer layer to attain a sensitivity of 3.191 μA/mg L −1 .nitride N3-phosphate PO 4 3-phosphite PO 3 3-phosphide P3-Name: Date: Created Date: 4/5/2017 11:40:28 AM ...Phosphate is a good choice too, hold oil well, isn't as flashy/blingy as chrome. Nitride is the 3rd choice, but still perfectly fine for any uses.. it's probably just slightly under phosphate just as a general 'coating'. you can read more up on phosphate vs nitride.. Most people here want the chrome cuz they like shinny things :D

Unlined barrels served this country well in 2 world wars and a Police Action in Korea. Properly maintain any barrel it it will usually last a a lifetime. Hotlink says nitride, pic in ad shows a nitrided barrel (see how glossy the barrel is compared to the FSB), but description says phosphate. Weird.Firearm Discussion and Resources from AR-15, AK-47, Handguns and more! Buy, Sell, and Trade your Firearms and Gear.

AR barrel steel is the base metal that the finish and coating goes over. As the foundation, it is important up to a point. There are four main steels used to create AR-15 barrels, the last of which could broadly be called “stainless steel.”. As it happens, several types of stainless steel are commonly used in barrel-making, which we’ll ...

A user asks for advice on choosing between phosphate or nitride finish for AR-15 barrels, based on the opinions of other users and experts. The consensus is that nitride is the better choice, except for phosphate barrels with chrome lining, which are not common or recommended.Figure2.7.3 2.7. 3: Example of some compounds that have multiple oxidation states. Note mercury (1) is not a monoatomic cation, but is really a homonuclear diatomic ion of two mercury atoms bound to each other, both having lost one electron. So Hg 2 Cl 2 it the lowest whole number ratio of cation to anion. Example 2.Finish - phosphate, chrome lined, nitride, as-is (stainless) Baseline is phosphate / parkerized (plus chrome lining for milspec). The chrome lining adds durability but reduces accuracy. This is because, as a plating, it changes the steel part's dimensions. Barrels intended to be chrome lined must be machined differently beforehand to account ...Unlined barrels served this country well in 2 world wars and a Police Action in Korea. Properly maintain any barrel it it will usually last a a lifetime. Hotlink says nitride, pic in ad shows a nitrided barrel (see how glossy the barrel is compared to the FSB), but description says phosphate. Weird.

In short, no. Standard phosphate BCGs will hold lube better but not be as slick. Nitride is slicker but does not hold lube as well. NiB is much like Nitride but may flake or chip. Personally, I use phosphate and Nitride carriers and have no desire to spend more money for something that does the job equally as well.

Phosphate finishes are just a coating, the are rough on the surface and hold oil well. Better than paint, better than blued steel. Nitride finishes are actual surface treatments to the metal. The high temperature process diffuses nitrogen into the metal actually changing its structure. The surface left is very hard and very corrosion resistant ...

Nitride doesn't flake, chip, or stain. The lubricity you get out of the box is the same you'll get 10k rounds later and probably far beyond that. If you really want an "exotic" finish/treatment on your carrier give hard chrome a look. Otherwise, good ole phosphate or nitride are proven.In general, “hardened” surfaces have a lower coefficient of friction, which aids in functioning and other features. Platings would include nickel boron, along with chrome, plain nickel, gold ...Made by one of the large popular OEM BCG makers who is also a military supplier. These BCGs are available due to a large OEM order being canceled. We purchased them all and are making them available to you at an incredible price. Their loss is your gain! These feature a Carpenter 158 Bolt, and a full profile chrome lined carrier.Geissele changed from mag phosphate aka parkerizing to black oxide. Nitride was always offered as an alternative. Secondly, this test is pretty useless. Nitride is on a whole other level as far as corrosion resistance. What people want to see is a comparison between mag phosphate and black oxide.Oxynitride. The oxynitrides are a group of inorganic compounds containing oxygen and nitrogen not bound to each other, instead combined with other non-metallic or metallic elements. Some of these are oxosalts with oxygen replaced by nitrogen. Some of these compounds do not have a fixed oxygen to nitrogen ratio, but instead form ceramics with a ...and the other part of the conversation "...nitride is cheaper, better tolerances, easier to clean...". one topic that always gets touched on is nitride is easier to clean and CP (chrome phosphate) holds oil better, but the discussion usually stops there even though the threads go on for multiple pages, but that is the major take away.

Nickel boron is a trash gimmick coating. Phosphate, nitride, chrome, and NP3 are the only right answers. NiB is not an upgrade in any way shape or form. It does not cost more to make than other coatings and there is 0 reason to pay more for it. It is only smooth until the point it begins to wear, and then it creates hot spots that can lead to ...Phosphorus-doped graphitic carbon nitrides (P-g-C3N4) have recently emerged as promising visible-light photocatalysts for both hydrogen generation and clean environment applications because of fast charge carrier transfer and increased light absorption. However, their photocatalytic performances on CO2 reduction have gained little attention. In this …

The nitride barrel life is all dependent on how you treat it. That being said, our nitride barrel life span for average use is 12,000 rounds. Only downside to nitride barrels are they do not break in over time, once you do you initial break in, the grouping you get is all your ever going to get until the barrel life has ended.Quoted: Nitride is a harder and slicker finish than phosphate. Nitride will wear better, last longer, and have less friction than phosphate. There's a reason metal cutting tools (end mills, boring bar inserts, etc) have nitride coatings instead of phosphate. There is very minimal wear surface on a bolt carier. Advantages and benefits of Ni B, nickel boron, and nitro met, salt bath nitride on AR bolt carrier group, barrel, and gas tube assemblies. This is an inexpensive modern technology process to protect the surface of alloy steel against wear as well as corrosion. The traditional manganese phosphate process on mil spec bolt carrier groups […]Phosphorus(V) oxide: Phosphorus(V) oxide reacts violently with water to give a solution containing a mixture of acids, the nature of which depends on the reaction conditions.

I'm usually a chrome lined hammer forged guy, but I want to keep this cheap. Posted: 10/20/2018 3:24:43 PM EDT ...Nitride is generally better. Phosphate is essentially parkerization, nitride is harder and more corrosion resistant. Chrome lining is a superior bore treatment - by a little bit and for some use cases - but phosphate is a vastly inferior exterior treatment for longevity and corrosion. And because it is two processes, it costs more vs 1 single ... CL barrels have a phosphate outer finish that SUCKS (scratches easily, is NOT corrosion resistant w/o constant oil wipes, etc). Nitride is cheaper AND better than CL in my book. I'm actually as happy with my Ptac nitride middy as I am with my FN CHF/CL middy, and that's saying a lot.Let’s discuss merits of Nitride vs. Phosphate for KISS handout rifles.
