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 ...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 …I have the choice between two 10.5" pistol build kits: one with a .223 wylde phosphate heavy profile barrel, another with a .556 NATO nitride A…Oxygen occurs in all kinds of minerals. Some common examples include the oxides, carbonates, nitrates, sulfates, and phosphates. Oxides are chemical compounds that contain oxygen and one other element. Calcium oxide, or lime or quicklime (CaO), is an example. Carbonates are compounds that contain oxygen, carbon, and at least one other element.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.

Both finishes are durable. Nitride is not only coated on the exterior, but in the barrel's bore too. It permeates the metal to give better rust protection. Phosphate is only done on a barrel's exterior surface and not the bore. This is because mil-spec type barrels are chrome-lined first and chrome won't stick to phosphate or any other coating ...A nitrate nitrite, or nitrite nitrate, is a coordination complex or other chemical compound that contains both nitrite and nitrate anions (NO 3 − and NO 2 −).They are mixed-anion compounds, and they are mixed-valence compounds.Some have third anions. Many nitrite nitrate compounds are coordination complexes of cobalt. Such a substance was discovered by Wolcott Gibbs and Frederick Genth in ...

jim browne chevrolet dade city 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. Liquid Nitriding (LN) is a common term for a diffusion process that is actually liquid nitrocarburizing; a thermo-chemical reaction whereby nitrogen, primarily, and some carbon are diffused into the surface of iron-based materials.

There is very minimal wear surface on a bolt carier.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.
