5 key takeaways from our most recent engineering video on anodizing: Anodizing isn't a coating. It's an electrochemical process that changes the surface of aluminum by growing a thicker oxide layer. Aluminum naturally oxidizes. When exposed to oxygen, aluminum immediately forms a thin protective oxide layer that helps prevent further corrosion. Electricity drives the anodizing process. By placing aluminum in an electrolyte bath and applying electrical current, we can grow a much thicker, more controlled oxide layer. The oxide layer allows for color. Anodizing creates a porous surface that can absorb dyes. A sealing process then helps lock in the color. Anodizing improves aluminum's performance. The thicker oxide layer provides better corrosion resistance, wear resistance, and electrical insulation while also allowing for cosmetic finishes.
