anodizing

Electrolytic surface hardening

Anodizing is an electrochemical process that thickens the natural oxide layer on metal surfaces, typically aluminum.

The resulting coating resists corrosion, accepts dyes for coloring, and provides a harder surface than untreated metal.

The bike frame was anodized in a deep blue finish.

Common in aerospace, cookware, and consumer electronics.
