Designed for aggressive wear and corrosion protection at high temperatures

nickel boron nitride

A Surface Solution for High Temperature Applications

Nickel-Boron-Nitride (NBN) coating is engineered for extreme wear and corrosion resistance at high temperatures, suitable for aggressive environments. This composite coating surpasses standard Nickel-Teflon in terms of friction performance and can withstand temperatures up to 1562°F.
The application of Armoloy's nickel boron coating results in a thin, even layer that adheres well to base metals without altering their geometry, making it ideal for precision components.

High Temperature Solutions from Armoloy

The Armoloy Corporation helps global manufacturers protect their most valuable, high-precision components with a broad spectrum of engineered surface coatings.

Nickel boron coating is primarily used in applications requiring high wear resistance and thermal stability. This includes plastic injection molds, automotive components, aerospace parts, and industrial machinery. It is especially beneficial for components like core and cavity blocks, lifters, and ejector pins in molding industries, where it significantly enhances the release properties and wear life.

The Science Behind Nickel Boron Coating

The nickel boron nitride (NBN) plating process, often referred to as electroless nickel boron (EN-BN) plating, is a highly advanced and technical method for applying a protective coating to various substrates. This process is autocatalytic, meaning it does not require an electrical current to deposit the nickel boron alloy onto the surface of a part. Instead, it utilizes a chemical reaction to achieve deposition. The solution used for NBN plating typically contains nickel ions and a boron-containing agent like sodium borohydride or an alkylamineborane, along with other chemicals such as buffers and complex agents to control the plating process.
