Anodizing of aluminium and its alloys

anodizing; anodisation

Electrolytic oxidation with aluminum as the anode. This process produces barrier or porous oxide layers, depending on the electrolyte chosen.

hard coat anodizing; anodisation dure

Anodizing process that produces hard, abrasion-resistant oxide layers.

sulphuric anodizing; anodisation sulfurique

Anodizing process where the electrolyte is sulfuric acid.

colmatage; sealing

The porous anodizing process closes pores and improves the corrosion resistance of anodized metal.

coloration chimique; chemical coloring/dyeing

After anodizing, colored pigments are chemically incorporated into the pores of the coating. This treatment is carried out before sealing.

coloration électrolytique; electrolytic coloring/electrocoloring

After anodizing, metal is deposited by electrolysis at the bottom of the coating pores....
