Phosphate vs nitride

In the PSA Freedom line, I prefer nitride because the phosphate freedom barrels are not chrome lined. The nitride treatment makes the steel more wear and corrosion resistant. Personally I like nitride, but there are some possible problems with it. I've read that the nitriding process heats the metal to over 1000 deg F.

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 ...What's the difference between Phosphate and Nitride? Been thinking about getting a PSA 10.5 upper for a Mk18/CQBRish Block I build. When trying to compare the uppers I see that there's a phosphate finish and a nitride finish. Made me think what's the real difference between the 2. Is one really better than the other? 3 14 comments Add a CommentBolt-carrier groups above, from left, represent Nickel Boron, phosphate (Palmetto State Armory), Robar NP3, black nitride and chrome-plate (Daniel Defense).Melonite and nitride are the same thing and better than phosphate. Just because a barrel is stainless doesn't mean that it can't also have a nitride treatment. Mega has 416R stainless barrels that are nitride treated. •Nitride does not affect the physical dimensions of the steel so it is preferred to chrome lining when seeking out 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 ...We can simply refer to the cation in the ionic compound as magnesium. Phosphorus, P , is a group 15 element and therefore forms 3- anions. Because it is an anion, we add the suffix -ide to its name to get phosphide as the name of the ion. Therefore, the name for the compound is magnesium phosphide.Phosphate vs Nitride Barrels. When you're building an AR, picking a barrel presents a dizzying array of choices, especially for the first timer. Everything…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.

Had phosphate, nitride and nib from AIM and just the phosphate PSA but all g2g. I too love the Toolcraft bolts they are great quality. With the nitride version barely above $70 no reason to go elsewhere. I've got an EXO, nitride and phosphate from them in addition to a Fail Zero and BCM BCG. They're top notchThere are benefits and drawbacks to both carbon and nitride barrels. Here are some things to consider when making your decision: -Cost: Nitride barrels tend to be more expensive than carbon barrels. -Longevity: A nitride barrel is more resistant to wear and tear, meaning it will last longer. However, a carbon barrel is easier to repair if it ...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.

Each ion: contains the same number of electrons (10; with configuration 1s22s22p6) and are thus termed a collection of isoelectronic ions. varies in the nuclear charge.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.Na 3 PO 4 (sodium phosphate) +5 : N 2 O 5 : P 4 O 10: The same factors that explain the differences between sulfur and oxygen can be used to explain the differences between phosphorus and nitrogen. 1. Nitrogen-nitrogen triple bonds are much stronger than phosphorus-phosphorus triple bonds. 2. P-P single bonds are stronger than N-N single bonds.Nitrate is a nitrogen oxoanion formed by the loss of hydrogen from nitric acid with a charge of -1, one nitrogen atom, and three oxygen atoms. It is a polyatomic ion with the molecular formula NO3- that is commonly used in the form of salts in fertilizers and explosives. Nitrate is a monovalent inorganic anion and a conjugate base of nitric acid.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 …

Popular methods for amorphous ZrP synthesis include the gel, sol-gel and template methods [55].In the typical gel method, amorphous ZrP is precipitated by mixing one solution with a zirconium source, usually zirconyl chloride octahydrate (ZrOCl 2 ·8H 2 O), and another solution with a phosphorus source, usually phosphoric acid (H 3 PO …This paper presents the effect of temperature to the etch rate of nitride and oxide layers in Buffered Oxide Etch (BOE) solution.

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 ...Pros for Nitride, chrome, nickel boron: easier to clean Cons: doesn't hold onto oil/lubricants as well but it's naturally a slicker finish I have a combo of all 3. Shooting with suppressors makes me like the phosphate a litter better cause shooting suppressed makes for an extremely dirty gun quick and the phosphate carrier holds onto oil better.

Choosing between Parkerized vs Nitride is a difficult task. Read on to get insights into 4 different parameters and choose an ideal finish for your gun. ... The difference between phosphate and nitride finishes lies in the coating process. Phosphate involves the application of a chemical coating. While gas nitriding modifies the metal's ...

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.PSA 16" Mid-Length 5.56 NATO 1/7 Phosphate 13.5" Lightweight M-Lok MOE EPT Rifle w/MBUS Sight Set ...

It seems like many well regarded companies are offering nitride/melonite bolts as a default these days. While it's certainly a more durable surface treatment than mil spec phosphate, I know there's a school of thought out there (& I'm sure @Constructor will be along shortly to give voice to it) that it negatively impacts the core steel's durability over time.QPQ Coating vs. Nitride. While both QPQ coating and Nitride create a layer of ε iron nitride on the material, they are not the same. They both indeed belong to the group of thermochemical heat treatments. Yet, there are important differences in parameters. These are the temperature used, the completion time, and the steps to complete the process.Nitride is billed as doing everything that chrome does but cheaper and supposedly has an advantage in that it's a treatment as supposed to a layer upon the metal like chrome plating. Phosphate is the standard finish. There for corrosion protection and nothing else.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.Nitride/Melonite is an alternate method of Heat Treating. It is a well proven industrial process to increase lubricity, resistance to wear, high temperatures, and stress. Nitride/Melonite has the benefit of superior corrosion protection that basic Mil-Spec hardening and Phosphate does not have.Stainless steel gives better accuracy but at the cost of lower overall barrel life. That being said the average shooter doesn’t shoot enough or accurately enough to benefit from stainless steel. Nitride from a production standpoint is also easier to make and generally translates to cheaper barrels/uppers but exceptions do exist. 2 Likes.Phosphate vs Nitride. These are two of the least expensive finishes available. Nitride has the edge when it comes to smoothness and hardness. It also requires less lubricant to work well and is easier to clean. Nitride has many advantages but it is not mil-spec for BCGs and that is an important consideration for some.17 nov 2021 ... ... nitride finish.

The physical vapour deposition techniques are widely used to deposit a wide range of materials on a number …Service life is not one set thing when it comes to nitride. It depends on the type of nitride used such as AMS 2753 vs AMS 2756, salt bath vs gas nitriding. Then there is the prep and execution. A properly prepared and performed nitride barrel will have a service life on par with a chrome lined for slow deliberate fire.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.
