That could also play a factor in the reduction in fingerprints, in addition to the new anodization. Follow Chance: Threads, Twitter, Instagram, and Mastodon. Add 9to5Mac to your Google News feed.

This process, called “droplet-scale anodization,” is not only simpler than existing manufacturing methods but also environmentally friendly, cutting down on chemical waste and energy use.

Pores are opened when the aluminum goes through anodization. Those pores are filled with dye, then the metal is boiled in water which closes them, sealing in the color. Pretty neat!

By use of anodization, in a simple, one-step process, nanostructured NiFe oxides were created on the surface of the NiFe foam. NiFe oxide was characterized using several techniques, which demonstrated ...

The ‘anodization seal’ to reduce fingerprints iFixit also has some speculation on the space black MacBook Pro’s fancy anodization seal, which cuts down on fingerprints: ...

With each transition to a new technology node, fab requirements for metal and particle contamination become more stringent, posing challenges for existing coating methods such as anodization or plasma ...

Then it’s on to anodization in a solution of sodium bisulfate, with a repurposed 12 V, 2 A power supply putting a bit of current through the piece. The trick is to realize this is anodization ...
