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.

How Metals Fail
Some of the most common metal failures include:
Armoloy’s different metal coating solutions help industries avoid costly metal failures and unplanned downtime.
Boron coatings are primarily used to improve surface hardness, wear resistance, and corrosion protection. They are often applied to cutting tools, machine parts, and metal surfaces to enhance durability and performance. Boron coatings can also provide thermal stability, making them suitable for high-temperature applications.
The hardness of nickel boron coating typically ranges between 65 to 70 HRC (Rockwell Hardness Scale), making it very hard and resistant to abrasion. This high level of hardness is beneficial for applications requiring robust protection against wear and tear, such as in firearms and industrial machinery.
Nickel boron nitride coatings are generally applied in thicknesses ranging from 0.0003 to 0.0007 inches. This thin yet effective layer provides significant enhancements in terms of hardness, corrosion resistance, and low friction, without altering the dimensions of the treated parts.
Nickel boron does not rust in the traditional sense as iron does, but it can corrode under certain conditions. This coating is highly resistant to corrosion, significantly reducing the risk of rusting on the coated surface. The protective layer created by nickel boron nitride prevents oxidation and other environmental factors that typically lead to rust.
