What Is Electroless Nickel Plating?
Electroless nickel plating is a method of depositing a layer of nickel-alloy on a substrate without needing an external electric current. This process involves a self-catalytic chemical reaction that causes nickel ions to bond to the substrate’s surface, facilitated by a reducing agent.
Its most notable benefit is the ability to achieve a uniform coating thickness across the entire surface of an object, irrespective of its shape. This uniformity is crucial for components that require enhanced wear and corrosion resistance, as well as consistent thermal properties. The electroless nickel plating process also results in a coating with very few impurities like carbon or sulfur, ensuring the plated layer maintains high purity with excellent physical and chemical characteristics.
