Phosphate vs nitride.

Selvia Saeed. View. Show abstract. ... Excess phosphates damage the kidney and lead to osteoporosis. According to Environmental Protection Agency (EPA), the recommended value of phosphorus in ...Go nitride. Better barrel life and reduced chances of corrosion. They do phosphate because it's cheaper and PSA is a "Value oriented" brand. If you watch their sales, the nitride can usually be found for the same prices as the phosphate regularly. Posted: 8/20/2021 6:23:35 AM EDT. Nitride is a better and less expensive surface than phosphate/chrome. The drawback is temperature sensitivity, but the relevant temperature is only reached with sustained full auto. If you don’t have full auto, there’s no benefit to chrome/phosphate. Any reputable company can dimension a machine part with either surface.Here’s a quick summary of the benefits of Melonite barrels: It is a single process in comparison to chrome plating that requires phosphating of the exterior barrel surface. Melonite coating dramatically increases corrosion resistance without oil using. Melonite protects the inside and outside of the barrel. Looking for a PSA Upper. PHOSPHATE finish. A2 front sight post with the PSA bolt carrier group. Furniture is no concern.

Thus, you may have massive demand for phosphate as it binds to bare calcium carbonate surfaces, but little demand for nitrate. Likewise, you may have substantial need for nitrate that is being consumed at least partly by denitrification, a process that doesn't consume phosphate. Mar 12, 2021. #7.Posts: 2,119. Nitrade vs. Nickel Boron BCG. Holiday sale. $80 for the Nitrade or $90 for the Nickel. I need a few and the $10 is immaterial if there's an actual performance difference. My biggest complaint of the AR is that it fouls the bolt badly and is prone to jamming due to the gas design. If I can improve the performance for the extra $10 ...

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 ...

Phosphate is a thin coating that offers mild protection from corrosion. Nitriding is a surface treatment that increases surface hardness and corrosion resistance of steel when done …Graphitic carbon nitride quantum dots (CNQDs) are a new class of nanomaterial with an extraordinary photoluminescent property. Here, three highly water-soluble and photoluminescent CNQDs are synthesized through a green and facile one-step hydrothermal approach, with urea as the nitrogen source and citric acid and its salts as carbon sources. The photoluminescence (PL) performance demonstrated ...I have BCM phosphate coated BCGs and I have a Rubber City Armory (RCA) black nitride coated BCG and all of which I shoot suppressed. The RCA BCG cleans up a hell of a lot easier than the traditional phosphate coated BCGs. I have also owned a Fail Zero but never shot it suppressed but it too cleaned up a lot easier than phosphate.The aim of this article was to deliver a review of the tribological properties of nitride-based coatings attained using various techniques including physical vapour deposition, chemical vapour deposition and spraying techniques. The physical vapour deposition techniques are widely used to deposit a wide range of materials on a number of base ...In chemistry, a nitride is an inorganic compound of nitrogen.The "nitride" anion, N 3-ion, is very elusive but compounds of nitride are numerous, although rarely naturally occurring. Some nitrides have a found applications, such as wear-resistant coatings (e.g., titanium nitride, TiN), hard ceramic materials (e.g., silicon nitride, Si 3 N 4), and semiconductors …

Phosphorus, on the other hand, is not directly affected by redox changes. Numerous studies have investigated the effects of redox on As distributions in wetland and sediment environments [31,32,33]. Studies on competitive reactions between phosphate and arsenate for uptake by plants are also numerous [27, 34, 35]. However, few studies …The AR-15 bolt carrier group, or BCG, is a critical and often misunderstood piece of the AR-15/M16 upper receiver. Here I will give a brief breakdown of the BCG's components, how it works, problems to look for and what to consider when buying. The image below gives a nice breakdown of the parts in a typical BCG. Courtesy Firearms History.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. ...Gallium nitride (GaN) is a compound comprised of gallium and nitrogen that work together to form a robust Wurtzite crystal structure. This structure is very strong and has a high melting point, 4532 degrees Fahrenheit, making it suitable for semiconductor base materials in high-temperature settings. GaN's structure will accept magnesium to form ...Given the efficient reaction of P-containing species with radionuclide U(VI), phosphate-modified carbon nitrides (GPCNs) were prepared with enhanced surface areas (16.9-102.0 m 2 /g) and abundant phosphate groups (15.8-9.1 at% of P) and applied to capture aquatic U(VI). GPCNs presented a fast equilibrium of 8 h, efficient capture capability (maximum 333.5 mg/g at pH 5.0 and T 278 K ...

Quoted: "Melonite" is a proprietary version of nitride. There are MANY types/versions of nitride. Typically, "Melonite" or anything labeled as QPQ nitride will have a textured/satin look to it, where as the cheaper/quicker versions of nitride (without the polish/quench done after the first treatment) will have the glossy (almost blued) black ...The top manufacturers still use chrome and they know more than me. Knights, LMT, BCM, COLT, DD. There are a few higher tier manufacturers using nitride like SOLGW and i am sure it is fine For BCG i usually just stick with phosphate 158 bolts, but havent read anything bad on Nitride ones. I would def choose it over NIB.Nitride is significantly less expensive and less time-consuming for making barrels. It is a single process versus chrome which requires both chroming and the …Nitride Interior; Phosphate Specs: These Military surplus 158 Bolt carrier groups are manufactured by AO Precision to the exacting standards of the US Military. AO makes these HPT / MPI BCG's for other Military contractor juggernauts, such as FN America. All bolts are rigorously inspected and are individually High Pressure Tested and then go ...Phosphate is a dull grey color and usually a little rougher. Nitride is usually black or blue and very smooth. One of nitrides positive attributes is that it is very slick and corrosion resistant. Old phosphate barrels can be a little slicker and shiny just from wear or exposure to lubricants.

Scenario: You're picking out a barrel for your new AR-15 rifle build. You discover you have a choice between a chrome-lined or a nitrided barrel. So which is...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 ...

Nitride makes the barrel apx 70 Rockwell, to hard to cut with anything but is not as resistant as chrome. Edited- after researching and talking to the company that performs this process it seems that both the inside and outside of the barrels are more resistant to the salt spray test than are chrome-lined barrels.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.Phosphate is just basic parkerizing and will provide minimum corrosion resistance. It’s also porous and will make cleaning more difficult. Nitride is even harder and more corrosion resistant than chrome lining and produces sharper rifling which increase accuracy.The Black Nitride coating vastly increases the hardness of the steel, prevents corrosion, is highly resistant to wear, will not flake (it's not a coating, it's a bond), and has increased lubricity when compared to a phosphate-finished BCG. The Bolt Carrier Group is the heart of your rifle, and if you want to upgrade the functionality of ...What is the difference between phosphate and nitride barrel? On the basis of performance, nitride wins. For nostalga, phosphate wins. The battle between these two smooth finishes comes down to cost vs performance. Both are excellent finishes that are very hard, smooth and high performing.Phosphate Coating. We will start with the most common coating. Phosphate coating, also known as manganese phosphate coating, phosphating, and Parkerizing, is a pretty simple process. The bolt carrier group is placed in phosphoric acid and heated up to around 200 degrees Fahrenheit. This coating is extremely common because it is inexpensive and ...Firearm Discussion and Resources from AR-15, AK-47, Handguns and more! Buy, Sell, and Trade your Firearms and Gear.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 ...The Toolcraft chrome phosphate BCG is true to the original in form, fit and function. Through a combination of both proprietary improvements (carrier steel) and modern improvements (Viton O-ring), the Toolcraft offering is at least as good if not better than the original. It's a solid choice that won't let you down.Oct 31, 2021 · 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.
