Aluminum naturally forms an oxide layer ... leading to the bright colors you often see on anodized pieces. In this process, the lye is used to strip the surface. Then it’s on to anodization ...

The hard anodization process makes the surface of the aluminum grainy which provides better protection from wear marks or scratches on its surface as well as providing more grip when handling it.

New solutions have been developed to address these concerns, including advanced anodizing processes ... enclosures A recent study evaluated process developments mitigating the impact of alloying ...

Transparent aluminum oxide (TAlOx), a real material ... allowing precise control over the anodization process. This new approach might make TAlOx cheaper and more accessible for applications ...
