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.
