What is Anodising?

Anodising is an electrochemical process used to create a protective oxide layer on the surface of metal parts, typically aluminium and its alloys. This process involves immersing the metal parts in an electrolyte solution and passing an electric current through them, which stimulates the formation of an oxide layer on the surface. The thickness and properties of the oxide layer can be controlled to achieve specific performance characteristics, such as corrosion resistance, hardness and colour.

How anodising works

During the anodising process, the metal part serves as the anode (positive electrode), while a cathode (negative electrode) is immersed in the electrolyte solution. When the electric current is applied, oxygen ions from the electrolyte react with the metal surface to form a porous layer of aluminium oxide. This oxide layer can then be further treated through processes such as sealing or colouring to enhance its properties and appearance.

The applications of anodising

Anodising has application across a wide range of industries and products, including:

  • Aerospace: Anodised aluminium components are commonly used in aerospace applications due to their lightweight, corrosion-resistant properties, as well as their ability to withstand harsh environmental conditions.
  • Architectural: Anodised aluminium is used in architectural applications such as building facades, window frames and curtain walls for its durability, weather resistance, and ability to be coloured to match specific design aesthetics.
  • Automotive: Anodising is used in automotive manufacturing for exterior trim, wheels and engine components to improve corrosion resistance, durability and visual appeal.
  • Consumer electronics: Anodised aluminium is widely used in the production of smartphones, laptops and other consumer electronics for its sleek appearance, scratch resistance and durability.
  • Medical devices: Anodising provides a biocompatible, corrosion-resistant surface for medical devices such as surgical instruments, implants and diagnostic equipment, ensuring patient safety and device longevity.
