Zirconium Nitride is one of the hardest of the Physical Vapor Deposition (PVD) hard coatings. Its unique characteristics have made it suitable for applications where Titanium Nitride has not performed well.

Zirconium Nitride won’t chip, peel, or flake. It also has the beautiful appearance of light polished gold making this PVD coating stand out from the rest.

This coating is one of the most superior applications for sticking and picking on tablet compression tooling.



Chrome based thin films have been widely used for hard film applications such as tools and dies due to their superior wear properties, corrosion and oxidation Resistance. Methods of applying the coating and/or film includes, electro-plating, hard-chrome, CVD, PVD, and etc.

Though the transition metal nitrides have good mechanical and tribological properties and high corrosion and wear resistance, due to their good chemical stability and high oxidation resistance. However, the elemental characteristic of relatively low hardness limits its full application potential.

The hybrid layer architecture of Zirconium Nitride decreases hydrodynamic interactions during mechanical movement of the parts during processing.

Transition metal oxynitride film, especially zirconium oxynitride (ZrOxNy), has attracted considerable interest in the last few years due to its remarkable properties. ZrOxNy thin films have been widely applied in gate dielectrics, temperature sensor elements in magnetic fields up to 32 T operating at temperatures between 2 and 286 K, corrosion resistance coatings, and decorative films such as eyeglass frames, wristwatch casings, and wristbands. The appearance of oxygen during the deposition process leads to a formation of ionic metal–oxygen bonds in a matrix of covalent metal–nitrogen bonds; it generates a new structure (metal–oxynitride) with different properties. This variation of the oxygen/nitrogen ratio allows us to tailor the structural, optical, mechanical and electronic properties of the transition metal oxynitride film to your needs.
