Phosphate vs nitride.

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 ...Photocatalytic H 2 O 2 production in pure water is prerequisite for diverse on-site applications, but challengeable to be realized owing to sluggish water oxidation and significant recombination of photogenerated charges. Herein, efficient photocatalytic H 2 O 2 production in pure water was realized on graphitic carbon nitride (GCN) decorated by …The decomposition of the same precursor (Ni(Ac) 2 ·4H 2 O) under similar reaction conditions but with HDA in place of TOPO yielded a different phase of nickel phosphide (), which was indexed to phase-pure hexagonal Ni 5 P 4 (ICDD #01-089-2588) and is henceforth referred to as NiP-2.

Nitride coating is the result of a heat process that creates a hard, nitrogen-based casing directly onto a surface. ... such as phosphate. The Cons of Nitride. Despite the benefits nitride coating offers, you should also know ...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 ...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.

Phosphate, AKA parkerizing, is an external surface coating that somewhat improves corrosion resistance, darkens the metal, and gives a harder rough finish. Nitriding (meloniting, QPQ, Tenifer, etc.) Is an external and bore treatment that greatly increases hardness and corrosion resistance similar to chrome lining/plating.

Feb 16, 2016 · 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.

MH Nitride (Melonite) is a chemical process performed at high temperature (975-1100 degrees) in a cyanate salt bath. The finish is on the inside and outside of the barrel. Glock uses this process and they call it Tenifer. 5.)Phosphate coating - common way the barrels are protected against the elements. Phosphate coatings are a crystalline ...Sodium chloride is an ionic compound made up of sodium ions and chloride ions in a crystal lattice. Image credit: Wikipedia Commons, public domain. Atoms are electrically neutral because the number of protons, which carry a 1+ charge, in the nucleus of an atom is equal to the number of electrons, which carry a 1- charge, in the atom.Ferritic nitrocarburizing or FNC, also known by the proprietary names Tenifer, Tufftride and Melonite as well as ARCOR, is a range of proprietary case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub-critical temperatures during a salt bath. Other methods of ferric nitrocarburizing include gaseous processes such as Nitrotec and ion (plasma) ones.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.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.

Parkerized vs Nitride. Parkerizing is a process that is used to protect the metal from corrosion. It involves coating the metal with a thin layer of zinc or manganese. ... Which is better black nitride or phosphate barrel? First, let's start with black nitride. Black nitride is a process that can be applied to both steel and aluminum barrels ...I also probably should have mentioned that the NiB BCG is a 9310 heat treated bolt, and the nitrided BCG is a shot peened 158 carpenter bolt. Nitride is pretty great, however I run NiB in all my rifles simply for the ease of cleaning. Also, Cryptic gang baby. I would try one of those out, the coating is unreal.
