Anodizing Heat Treatment

What is Anodizing Heat Treatment?

Anodizing heat treatment is an electrochemical process that forms a protective oxide layer on the surface of metals, enhancing corrosion resistance, providing an aesthetic appearance, and increasing wear resistance. It is commonly used for aluminum and aluminum alloys and is also preferred for paintable, decorative coatings.

How is Anodizing Heat Treatment Applied?

  • Preparation Stage: The metal surface is cleaned and freed from any oil, dirt, or existing oxide layers.
  • Electrolytic Bath: The metal is immersed in an electrolytic solution such as sulfuric acid or chromic acid and connected as the anode (positive electrode).
  • Application of Electric Current: A direct current is applied to create a controlled oxide layer on the metal surface.
  • Coloring and Sealing Stage:
    • Pigments can be added to the oxide layer for coloring.
    • In the final stage, sealing is performed in water or chemical baths to enhance durability.

Advantages of Anodizing Heat Treatment

  • Increases corrosion resistance.
  • Enhances surface hardness and wear resistance.
  • Provides an aesthetic and decorative appearance.
  • Can offer electrical and thermal insulation.
  • Improves adhesion of paint and adhesives.

Which Materials Is It Used For?

Aluminum and aluminum alloys
Titanium
Magnesium
Stainless steel (in some special applications)
