‘SEALING’ of oxide coatings produced on aluminium and its alloys by anodic treatment in sulphuric acid solutions is the reaction between the amorphous alumina (containing about 15 per cent ...

Anodizing services for finishing aluminum alloys employ electrolytic oxidation of the aluminum surface to produce a protective oxide coating. The anodic coating consists of hydrated aluminum oxide. It ...

Aluminum naturally forms an oxide layer on its surface when exposed to air. Anodizing in an electrolytic cell creates a thicker oxide layer that makes the part more resistant to corrosion and wear.
