Anodizing vs Electroplating


(2003)

Could someone briefly distinguish between anodizing and electroplating. The EPA list emission factors for these two operations so there appears to be a difference.

In anodizing, the part is made anodic which builds an oxide film on the parts in question, Eddie; in electroplating, the part is made cathodic and metal (usually a different metal than the substrate) is deposited onto it.

It's usually impossible to answer a question both briefly & correctly when it is posed without context, so if this didn't do it, please re-post with your own situation. Good luck.
