Chrome lining is the more traditional way of producing barrels on an arsenal level scale, as nitriding was a more expensive process. This has changed in recent years, and nitriding an entire barrel'd action is coming into vogue. The high temperature parts in your cars engine are nitrided vs chromed, for instance.Nitride, Melonite and phosphate are all surface treatments - not coatings. If it says the barrel is nitride finished, it means the barrel is finished with a nitride treatment - and all that entails. If it is finished in phosphate, it is finished with a phosphate treatment of the barrel.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 ...Sep 16, 2022 · Nitride is better than a plain phosphate barrel.

An ion is an element ...MIL-SPEC is manganese phosphate, which requires oil to provide excellent corrosion resistance on the outside of the barrel. Mag phos typically has a matte grey finish. Nitride. Instead of adding material to the bore (like Chrome lining), Nitride treats the existing steel by imbuing nitrogen into the steel itself.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.Phosphate is being phased out of most grass fertilizers-bad for lakes and streams. Causes algea and all kinds of things to grow in super abundance. Phosphate is a metal treatment to impart corrosion resistance.

This particular finish produces a robust hardness that’s pretty much second only diamonds! Anodizing requires initiating an electrochemical process that helps to protect steel against corrosion.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 built in lubricity, still needs lube just not quite as much. Stainless steel barrels are used for long range accuracy.Nitrocarburization is a thermochemical diffusion process. Nitrogen, carbon, and a very small number of oxygen atoms diffuse onto the surface of steel or other ferrous alloys. This forms a surface compound layer and a diffusion layer. There are two types of nitrocarburizing. Both types are low temperature, that is between 490°C and 580°C.Above: After 1100 rounds this Toolcraft BCG is filthy but the AR15 continues to run reliably.
