How Nickel is Used in Plating

Nickel plating is a vital industrial process that applies a thin layer of nickel to a substrate, enhancing its appearance, durability, and functionality. This process is widely used across various industries due to nickel’s versatile properties, which include corrosion resistance, wear resistance, and excellent adherence to diverse materials. Below, we explore the main methods of nickel plating and their applications.

Electroplating with Nickel

Nickel electroplating is a widely employed technique where an electric current is used to deposit a layer of nickel onto a surface. This method allows for customisation by altering the electrolyte composition and operating conditions, providing tailored solutions for different applications.

Electroplated nickel is commonly used to enhance the visual appeal of products such as automotive parts, bathroom fittings, and consumer electronics. Additionally, it improves the corrosion resistance and durability of items subjected to harsh environments.

The commercial importance of nickel electroplating is evident, with over 150,000 tonnes of nickel being deposited globally each year. Advances in this technology have also made it a go-to choice for applications requiring both functionality and aesthetics.

Electroless Nickel Plating

Electroless nickel plating employs a chemical process to deposit a uniform nickel coating without the need for an electric current. This uniformity makes it ideal for complex shapes and components requiring precise coatings. Applications include automotive brake systems, pumps, valves, and electronic components.

Electroless nickel plating is particularly beneficial for materials like aluminium, commonly used in aerospace and automotive industries due to its lightweight properties. For instance, electroless nickel coatings protect critical automotive components, such as fuel systems and turbochargers, from corrosion in harsh environments.

Electroless nickel plating also finds extensive use in aerospace applications, where safety and reliability are paramount.
