Design Defined: Anodize

Design Defined: Anodize




To anodize means to use a chemical process where a coating is etched onto metal.

Here is what Wikipedia has to say about anodizing,

“The process is called anodizing because the part to be treated forms the anode electrode of an electrical circuit. Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than does bare metal. Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light.”

Here is an example of anodizing in action:

Pretty neat, isn’t it?  I didn’t fully understand anodizing until researching this blog post.  I don’t think I’ll ever look at my phone or laptop the same way.

What do you think?  Are you enjoying/learning from these Design Defined posts?  I would love to hear from you.
