Damage Industries also lets you pick phosphate vs nitride, and has different dimpling if that matters to you. I think a "Slabside lower (601)" or "Partial Fence Lower (XM177E2)" may be appropriate. But Brownells has stopped making them. Look for the magazine release and front detent pin. That's the part for looks.Therefore, in this study, ultrathin and amorphous cobalt-nickel-phosphate (CoNiPO x) nanosheet arrays are deposited over vanadium (V)-doped cobalt-nitride (V 3%-Co 4 N) crystalline core nanowires to obtain amorphous-shell@crystalline-core mesoporous 3D-heterostructures (CoNiPO x @V-Co 4 N/NF) as bifunctionalManganese phosphate is a good finish for AR15 barrels as it creates a tough matte finish that’s anti-reflective, durable and its properties excel at holding oil. ... Nitride Coated. In 2021, nitride coated AR15 barrels are the most common finish you’ll see regardless of quality, type or brand. Why is this? It’s because the process of ...Nitride is easier to clean. While properly performed nitrocarburization treatment is great for a bolt carrier, it is a sub-par choice for the bolt. Reason being is that the nitriding process has the tendency to impart brittleness. This translates to decreased bolt life, usually significantly. The nitriding process involves submerging the steel ...IMO, the Black Nitride finish is the best bang for the buck of the black BCG finishes. It is a super hard finish that runs smooth and is both easy to clean and easy on the wallet. For a comparison of the top 3 black BCG finishes see our article The Best Black BCG Finish - Phosphate vs Nitride vs DLC .The structure of α-ZrP was obtained from single crystal X-ray diffraction measurements [20]. α-Zirconium phosphate was found to consist of layers where zirconium atoms are alternately above and below the central planes (Fig. 1).Each zirconium atom is bonded to six HPO 4 2− groups..

Nitride has a very smooth almost polished finish that is much easier to clean and slides in the upper much easier. how ever fn is doing there mil spec is how i,d do it personally. there engineers are alot smarter than me. Phosphate is often the limiting nutrient for algae growth and excessive level of phosphate can be fueling the growth of algae. Too much phosphates can also inhibit calcification in corals, while no phosphate at all can starve corals. The ideal levels for phosphate are below 0.02ppm, however, like Nitrates, it depends on who you ask.Go nitride if you can. Phosphate has a rougher surface, it's good at trapping oil and I DO recommend you keep it well oiled. Nitride is slicker and has better rust resistance, im not sure if it's any better for wear but ya.. go nitirde if you can. NITRIDE!!!!! Go nitride, they are maybe $5 more and well worth it.The Best Black BCG Finish - Phosphate vs Nitride vs … AR15 BCG finishes (l-r) Toolcraft Titanium Nitride, BCM BCG with Robar NP3+, Toolcraft Nickel Boron, Toolcraft Black Nitride, Colt BCG refinished in Chrome with Nickel Boron Gas Key, Toolcraft Diamond Like Carbon (DLC) Finish, Toolcraft Chrome Phosphate (Parkerized) There are a wide variety of finishes available for AR-15 bolt carrier ...Oxygen occurs in all kinds of minerals.

It's a solid choice that won't let you down.The etching rate of silicon nitride against the averaged fluid height at various rotation speeds. Figure 5 clearly shows the linear dependence of the Si 3 N 4 etching rate on the average fluid height at three rotation speeds (10, 30, and 50 rpm). The point of 100 rpm is out of this linear correlation, probably due to a too short retention time ...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 ...I’ve read that the nitriding process heats the metal to over 1000 deg F. Although it hardens the metal surface very well with the chemical process, the heat could cause problems with metal’s tempering. They were saying that the military prefers phosphate and that might be a reason.Another type of gun coating that’s particularly popular for internal components is the nitride coating. There are generally two types: Ferritic Nitrocarburizing and “Queen Polish Quench.” You might be more familiar with the latter through names such as Melonite, Tenifer, or Tufftride.Titanium Nitride. This offers BCGs excellent durability, plus slickness and smoothness in operation. Titanium nitride is tougher than nickel boron and phosphate coating, often resulting in longer carrier group service life. Coated steel has unmatched heat and corrosion resistance capabilities since nitride changes its molecular structure.Many people ask about the differences between nitric acid and citric acid for passivating parts made of stainless steel (SS), titanium (Ti), and other alloys. Both nitric acid and citric acid are effective in passivating many grades of stainless steel, and both methods are described in detail in the industry standards ASTM A967 and AMS 2700.Here are some key differences between the two types of batteries: Composition: LiFePO4 batteries use lithium iron phosphate as the cathode material, while lithium-ion batteries can use various cathode materials, such as cobalt oxide, manganese oxide, or nickel oxide.

The black nitride is the finish over the barrel inside and outside. It is not a Chrome Lined barrel. This is correct. Chrome-moly is a steel alloy used in everything from bicycles to guns.Nitride vs Phosphate. PSA Products. AR-15. Lobster July 17, 2021, 10:40pm 1. I have read some about Nitride and Phosphate barrels. I was wondering if you guys have a preference? For a range/home gun, not something for the jungle. 1 Like. GuitarGuy July 17, 2021, 11:33pm 2. I prefer Nitride simply for its corrosion resistance. ...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.My WMD NiB-X has had zero extraction issues. Perhaps the phosphate bolt in nitride carriers is that the temperature to do QPQ properly is very close to that which could soften the temper on the bolt. That could be dangerous. Been using a QPQ extractor for well over 2000 rounds suppressed on my DDM4 16.1" Middy.Scenario: You're picking out a barrel for your new AR-15 rifle build.

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.AR-15/.223/5.56 Stainless Steel Competition Cylinder Muzzle Brake Or Nitride Finish.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.phosphate (ZnCaPh) Phosphates were originally limited to sliding applications (plain bearings and cages) but can also be applied to rolling bearings The soft and porous layer is a very good lubricant reservoir, especially MnPh Nickel-phosphorus (NiP) NiP is a chemically produced nickel coating By changing the amount of phosphorus,Pool Phosphate Removal Tips: 1. Before testing for phosphates, water should be balanced, and chlorine level below 5 ppm. 2. Algae should be treated and pool clean before testing and treating phosphates. 3. Correct the source of the phosphate contamination, or use weekly maintenance dosage. 4.Magnesium nitride reacts with water to produce magnesium hydroxide and ammonia gas, as do many metal nitrides . In fact, when magnesium is burned in air, some magnesium nitride is formed in addition to the principal product, magnesium oxide . Thermal decomposition of magnesium nitride gives magnesium and nitrogen gas (at 700-1500 °C).Compounds between metal and nonmetal elements are usually ionic. For example, \(\ce{CaBr2}\) contains a metallic element (calcium, a group 2 [or 2A] metal) and a nonmetallic element (bromine, a group 17 [or 7A] nonmetal). Therefore, it is most likely an ionic compound (in fact, it is ionic).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 …Heat of Vaporization. (N2) 5.56 kJ/mol. 51.9 kJ/mol. Material Properties.

Think guns like a full size FN 509, Shadow Systems XR920, I have a full-size Walther PDP with a 4" barrel, etc. It's my preferred 9MM size gun for ...Black oxide is bluing. There are a few different methods to produce bluing but black oxide is the standard one today. Like nitride, what it actually looks like depends a lot on the final metal finishing. Could be dull, could be shiny, could be blue, could be black. It's not what I would consider one of the better modern finishes but that's your ...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. I personally prefer nitrided over phosphate, they clean up easier, however some nitride finishes are better than others where as phosphate finishes seem to a more consistent process. Always get nitrided. Nitriding converts and hardens the surface to improve durability and corrosion resistance. Phosphating is a coating that is meant to hold oil ...Just a few of the articles I have read can be found with a quick search and many more I'm sure with some digging around. In comparison of wear and corrosion restistence there is no way in hell that an untreated exterior barrel steel is tougher or more corrosion resistant than a nitride barrel when coated with phosphate.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. Only one acid is commonly considered, phosphoric(V) acid, H 3 PO 4 (also known as phosphoric acid or as orthophosphoric acid). \[P_4O_{10} + 6H_2O \rightarrow …Regular and phosphate are the same, phosphate is the mil spec coating. Similarly, nitride and melonite are the same thing. Phosphate is just fine, requires plenty of lube, but will last a long time. Nitride is a chemical treatment of steel that hardens the steel quite a bit (just the outer layer) and leaves a very smooth finish that has some ...This type of barrel is usually the most accurate, all other factors remaining equal. "Nitride" barrels are essentially the same as Chrome-Moly, but have undergone a plating process that creates a very tough surface strength. The obvious result is that is wears very well, and is purported to be very durable.Nov 24, 2014 · None of those is superior to mil-spec phosphate coating. Military experimented with hard chrome and nitrided BCG's early in the development of the M16. The original AR15 spec'd a full coverage HC coating. Resulted in increased failures due to cracking at high stress points. There is no performance reason to chose anything besides a phosphated BCG. 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 ...The AR-15 bolt carrier group, or BCG, is a critical and often misunderstood piece of the AR-15/M16 upper receiver.

Courtesy Firearms …. Hard coat anodize in the upper is around low to mid 60'sPhosphate provides better results than nitride and BCM is a You still have to get a good blank. What I am saying is that unlike chrome, it doesn't make the barrel's accuracy WORSE. Both extend life similarly. Hence, nitride is the superior treatment unless you have a belt-fed where chrome really starts to shine. Outisde of that, nitride is basically always a better choice all else being equal.nitride films and concluded that the silicon nitride films deposited via PECVD, unlike the other two deposition techniques, were more ... concentration of many different and dissociated phosphate and aqueous species8 and electrical conductivity is the result of a Stokesian, water diffusion-controlled, ion transport mechanism. ... Nitride is harder and cannot flake off as 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.
