"In some embodiments, the oxide coatings are applied to substrates composed of metals other than titanium or titanium alloys, such aluminum, aluminum alloy, steel, magnesium, magnesium alloys, zirconium, or zirconium alloys."

LQMT Blog: "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."
