However, chrome plating is routinely removed for many reasons. A nickel boron bolt carrier group will have greater lubricity and corrosion resistance than both chrome and nitride BCGs. Barrel pitting was one of the reasons I got involved in Salt Bath Nitriding. Chrome lined barrels are typically phosphate parkerized to protect the exterior steel from rusting, but this exterior finish does not offer the same level of corrosion resistance offered by the salt bath nitriding treatment. I Holland’s PharmaCote ® range is a suite of treatments and coatings that enhance the performance of substrate material for punches and dies. If corrosion is allowed to occur pitting will result and that will ruin accuracy for sure. Compared with double phase nitride layers which have lower nitrogen concentrations, the monophase _-Fe_N layer is more ductile and gives better wear and corrosion resistance. Even when using corrosive primed ammunition for the last50-60 yeatrs in commbloc weapons. Methods of applying the coating and/or film includes, electro-plating, hard-chrome, CVD, PVD, and etc. This coating is designed to replace hard chromium (hard chrome) with its superior resistance to adhesive wear, chemical corrosion, and oxidation. Nitride treats both the inside and the outside of the barrel and does not require any oils to provide the best corrosion protection. Harder than chrome and more corrosion resistant than phosphate, nitride is now the standard for BCG finishes. Custom coatings can be designed to meet specific hardness, durability, and corrosion resistance specifications. Plus nitride protects against corrosion too. Titanium Nitride (TiN) Balinit A b: 90 RC Miccrolloy Nickel Boron has a wide range of applications and has been rapidly embraced by the aerospace and automotive industries because it is harder than hard chrome, with higher corrosion protection.
