Mixed Oxide Finish


Coating amorphous metal parts is similar to coating most other metal components. Some processes work better than others, but overall, conventional methods work well. One coating that the Liquidmetal team recently examined is both cosmetic and functional: mixed oxide finish. The process creates a very thin native layer of the native metal alloy atoms in their oxidized states, making the material scratch resistant and colored.

Although thin (approximate thickness is 2 um depending on the color), the mixed oxide layer is extremely hard (around 1400 Vickers) and can be effectively used to resist scratching, wear, or other abrasive environments.
