Metal is weak to acid, moisture, and wear. You can enjoy the benefits without the downsides by finding the perfect coating or finish.
Electroplating
A chrome, gold, or electroless nickel coating is applied using an electric current. This achieves a thin metallic coating that separates the substrate from environmental forces that can cause wear. Businesses such as https://www.poeton.co.uk/surface-treatments/plating/electroless-nickel-plating/ can find the ideal metal coating for your unique requirements.
Powder Coating
Dry powder coating is applied to a metal surface and cured at high temperatures. The result? A thick, coloured finish that lasts between 15 and 20 years. Powder coating can resist both rust and chemicals, but when used for exterior surfaces, its lifespan is halved.
Sandblasting
When sand, grit, or other abrasive materials are propelled at high pressure, they clean metal surfaces, remove contaminants, and achieve a distinctive matte finish.
Passivation
In most cases, passivation relies on nitric acid to remove iron from the surface. It leaves an oxide layer behind to prevent rust.
Anodising
Anodising is usually reserved for aluminium substrates. It’s achieved through an electrolytic process that makes the natural oxide layer thicker. This amplifies the substrate’s rust resistance and hardness while making the surface capable of holding dye.
Hot Dip Galvanising
This method is achieved by submerging iron or steel in molten zinc. It creates a thick coating that prevents corrosion.
Coatings and finishes can allow you to achieve the precise properties that suit the environment your substrate is destined for.
