Production Coating Services

There’s a reason that WMD is called “The Arsenal of Firearm Plating Technologies.”

It’s because WMD offers a full spectrum of firearm-specific coatings, ranging from decorative ceramic topcoats to high-performance proprietary coatings, they include as follows:

NiB-X® Nickel Boron

NiB-X® is our proprietary formulation…and a remarkable technology that proves that not all nickel boron coatings are created equal. WMD was a pioneer in of nickel boron technology in the firearms industry, and not only is our coating formula unique; our application process is, as well. We’re confident that our NiB-X coating provides the optimal combination of hardness, wear resistance, lubricity, and corrosion resistance.  The coating has a Rc 70 and a coefficient of friction of .06.  NiB-X maintains its properties in high temperature applications and impervious to most chemicals (Nitric Acid notwithstanding).  It has the same material properties throughout the structure of the coating so integrity and properties are maintained throughout the thickness. Coating can be duplexed with sublayers or topcoats to enhance specific properties customers may desire.

Nitromet Salt Bath Nitrocarburizing (Melonite, Tennifer, Black Nitride)

This process is the new industry leader in bore coatings for firearm barrels—achieving a 30% greater lifespan in the bore than chrome!  It provides a Rc 55 surface through a high temperature diffusion process.  This technology is applicable to metals that can withstand the processing temperatures such as barrels, gas blocks, magazines, steel receivers, etc.

Electroless Nickel (EN)

An Electroless nickel coating is a dense alloy of nickel and phosphorus. Our engineered Electroless nickel plating processes can be tailored to provide various levels of hardness, wear, abrasion and corrosion resistance, and lubricity. We offer Low, Medium, and High Phosphorous plating processes, as well as Electroless Nickel with Teflon, EN with Boron Nitride, and black EN plating.

Electroless Nickel with Teflon

This coating is an electroless nickel with Teflon particles co-deposited within the matrix. The coating is designed to release Teflon particles, the nickel wears and more Teflon releases. Usually used for release properties in the mold and die industry. Limited wear and high temperature applications.

Black Nickel with Boron Nitride

This coating withstands higher temperature and pressures better than EN Teflon.The boron nitride particles are a much better choice than Teflon for firearms applications.  Still not as wear resistant as NiB-X but suitable for some wear applications.




All WMD finishes are applied in a facility that has earned NADCAP accreditation—the highest level of process control recognized in the aerospace industry! Our NiB-X coatings are certified to ASTMB607 and/or AMS2433C.  Nitromet conforms to ASTM 2753.

As important as the technologies themselves, we’re gun guys just like you! We’re experts in all the tolerances and variables that are crucial for optimizing firearms performance. Plus we do extensive range testing to insure our coatings last and meet your most demanding performance standards.
