The zirconium and titanium based Liquidmetal alloys achieved yield strength of over 1723 MPa, nearly twice the strength of conventional crystalline titanium alloys (Ti 6 Al 4 V is ~830 MPa), and about the strength of high-strength steels and some highly engineered bulk composite materials (see tensile strength for a list of common materials).
Another technique first applied to quartz and topaz has also been adapted to cubic zirconia: An iridescent effect created by vacuum-sputtering onto finished stones an extremely thin layer of a precious metal (typically gold), or certain metal oxides, metal nitrides, or other coatings. [14] This material is marketed as "mystic" by many dealers.
Wah Chang Corporation was an American manufacturing company in the metal or alloy industry based in Albany, Oregon in the United States. Since 2014, it has been a business unit of Allegheny Technologies and makes corrosion-resistant metals, such as hafnium, niobium, titanium, vanadium, and zirconium.
Zirconia is also employed in the deposition of optical coatings; it is a high-index material usable from the near-UV to the mid-IR, due to its low absorption in this spectral region. In such applications, it is typically deposited by PVD. [22] In jewelry making, some watch cases are advertised as being "black zirconium oxide". [23]
Corrosion resistance of zirconium alloys is enhanced by intentional development of thicker passivation layer of black lustrous zirconium oxide. Nitride coatings might also be used. Whereas there is no consensus on whether zirconium and zirconium alloy have the same oxidation rate, Zircaloys 2 and 4 do behave very similarly in this respect.
According to EN 13523-0, a prepainted metal (or coil coated metal) is a ‘metal on which a coating material (e.g. paint, film…) has been applied by coil coating’.When applied onto the metallic substrate, the coating material (in liquid, in paste or powder form) forms a film possessing protective, decorative and/or other specific properties.

When applied using the physical vapor deposition coating process it is commonly used for coating medical devices, [5] industrial parts (notably drill bits), automotive and aerospace components and other parts subject to high wear and corrosive environments. Zirconium nitride was suggested as a hydrogen peroxide fuel tank liner for rockets and ...
