Metal finishing has been around for thousands of years, and it has changed alongside human invention. From the bronze artefacts of ancient times to today’s advanced finishes like electroless nickel coating, the way we treat metal shows how our tools and technology have developed over time.
The Early Ages: Art and Protection
In the past, people used metal finishes mainly for decoration and protection. The Romans added gold, silver and bronze to items made of metal, like jewellery, tools and armour.
These processes were simple and done by hand, and they involved polishing or basic chemical reactions. Even then, the goal was to make objects look valuable, prevent them from being damaged and help them last longer. These early techniques led to things becoming more advanced in later historical periods.
The Industrial Age: Speed and Strength
Everything started to change in the 20th century. This is because, with all the factories and two World Wars, industries needed metal finishes that could be made quickly and would make products stronger and longer-lasting.
Electroplating became an important method as it used electricity to apply a layer of metal to another surface. This process provided better protection against rust, and also improved the look of products. It’s still used today in many different industries, including electronics and aerospace.
Other methods, like anodising and chromate coating, were also developed. They helped industries like defence and construction meet high demands for quality and durability.
Modern Day: Smarter and Greener
Today, metal finishing is more advanced than ever. It’s still about being strong, but it’s also about being an efficient process that is kind to the environment.
Processes like electroless nickel coating, like the examples seen at poeton.co.uk/surface-treatments/plating/electroless-nickel-plating/, allow metal to be coated without electricity. This process is great for parts that have unusual shapes, and it gives strong and even protection.
What’s Next?
In the future, metal finishing will continue to improve with smart coatings, new materials and greener solutions. Whether it’s for industrial parts or custom-made pieces, selecting the right finish helps protect materials and also helps the planet.
