Metal plating plays a crucial role in modern manufacturing, offering protection, improved function and aesthetic appeal to countless components across many industries. It involves applying a thin layer of metal to a base surface to enhance its properties, especially when the underlying metal is prone to corrosion or wear. From electronics to automotive parts, metal plating extends product lifespan and optimises performance.
Benefits Beyond Corrosion Resistance
While corrosion resistance is a primary reason for metal plating, its benefits extend much further. Plating can increase a component’s strength and durability, reduce friction and enhance electrical conductivity. It’s also widely used to improve surface adhesion for paint and coatings. In industries such as electronics and aerospace, precision is everything, and plating processes like zinc nickel plating are invaluable.
Zinc nickel alloys, in particular, are known for their exceptional corrosion resistance and ability to withstand extreme environmental conditions. This makes them ideal for automotive and defence applications. Additionally, plating adds aesthetic value, making even inexpensive materials look like high-end finishes, as seen in fashion accessories or household items.
The Evolution and Application of Metal Plating
The history of plating stretches back to the early 19th century, when Italian chemist Luigi Brugnatelli first achieved gold electroplating. Though his work was initially suppressed, later developments by English and Russian scientists brought plating into industrial use. By the 1940s, silver-plated items were commonplace in UK homes, thanks to advancements in mass production.
Today, electroplating and electroless plating are the two most common methods. The former uses electric currents, while the latter relies on chemical reactions to deposit the coating. Industries apply these methods to improve component performance in sectors as diverse as automotive, computing and consumer goods.
For example, electroless nickel plating offers magnetic benefits essential to hard drives and zinc nickel plating shields engine parts from heat and corrosion.

Without metal plating, modern devices and infrastructure would be far less efficient or durable. From aesthetics to function, the benefits of plating are deeply embedded in our everyday lives.
