Anodising

An electrolytic process that thickens and controls the natural oxide film on aluminium and certain other metals, improving corrosion and wear resistance and allowing the surface to be coloured by dyeing before sealing. It is widely specified for architectural aluminium and for aerospace components.

Also known as: anodizing, anodic oxidation

Related terms

Passivation

The formation of a thin, stable oxide film on a metal surface that markedly reduces its chemical reactivity, occurring naturally on metals such as stainless steel and aluminium or induced deliberately by chemical treatment. Passivation treatments for stainless steel remove free iron contamination and restore the protective chromium rich oxide layer.

Powder coating

A dry finishing process in which electrostatically charged powder, commonly polyester, epoxy or hybrid chemistry, is sprayed onto an earthed component and then fused and cured in an oven to form a continuous film. The process is essentially solvent free and allows overspray to be recovered and reused.
