About Chromium Nitride CrN Powder:
Chromium nitride is an extremely hard, inert film coating used primarily for precision metal parts. Chromium nitride (CrN) has stronger high-temperature resistance than tin, making it an ideal choice in high-temperature environments. CrN also performs well in corrosive environments and sliding wear applications.
Using cathode arc plasma deposition technology. Cathodic arc plasma deposition is a relatively new thin-film deposition technology, which is similar to ion deposition technology in many aspects. Its advantages are high ionization rate in the stream of emitted particles, and these ionized ions have high kinetic energy (40-100eV). Many advantages of ion beam deposition, such as adhesion enhancement, increased density of states, high reaction rate to compound film formation, are reflected in cathodic arc plasma deposition. Cathode arc plasma deposition has its own unique advantages, such as the deposition on a more complex shape substrate, high deposition rate, good coating uniformity, low substrate temperature, easy to prepare ideal chemical ratio of compounds or alloys.
The evaporation of cathode materials by the evaporation process is due to the high current density, and the resulting evaporates consist of electrons, ions, central gas atoms and particles. At the cathode arc point, the material is almost 100% ionized, where ions are emitted almost perpendicular to the surface of the cathode. When high-energy chromium ions encounter nitrogen, they react immediately, turning into gaseous chromium nitride molecules.

How is Chromium Nitride CrN Powder produced?
CrCl3 and NaN3 were used as raw materials for the preparation of chromium nitride at high temperature and high pressure, and the reaction rate was reduced by adding NaCl to ensure the safety of the experiment and the stability of the cavity. For the consideration of possible gas release and synthesis safety, the molar ratio of NaCl to NaN3 is added at least about 2 times to reduce the reaction rate, that is, the molar ratio of N2 to NaCl is at least 1 times to fully release the gas. The initial bulk sample was synthesized by adjusting the reaction temperature and reaction time, and the reaction products were CrN and NaCl, and the high purity CrN was obtained by washing.
Applications of Chromium Nitride CrN Powder:
CrN is used as a corrosion-resistant coating material in metal forming and plastic forming applications. CRN is commonly used in medical implants and tools. CrN is also a valuable component in advanced multi-component coating systems such as CrAlN for hard wear cutting tools. In addition, applications of chromium nitride include:
Higher temperature applications
Sliding wear application
Wear resistance of precision components
Eliminate wear, fretting, micro-welding, clamping and adhesion wear
Enhanced corrosion resistance, but not complete encapsulation of parts
Low friction
It can accommodate sharp edges
Small size effect, very suitable for small tolerance parts
The fundamental material physics of CrN has recently been debated in prestigious scientific journals such as Nature Materials due to its good properties. In particular, the importance of magnetism in both low and high-temperature phases has been demonstrated through quantum mechanical calculations of the electronic structure of compounds.
