How is chromium nitride CrN powder produced
Chromium nitride CrN uses CrCl3 and NaN3 as raw materials to prepare chromium nitride under high temperature and high pressure. The addition of NaCl can reduce the reaction rate to ensure the safety of the experiment and the stability of the cavity. In 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 time to completely release the gas. The initial block samples were synthesized by adjusting the reaction temperature and reaction time, the reaction products were CrN and NaCl, and high-purity CrN was obtained by washing.
Overview of chromium nitride CrN powder
Using cathodic arc plasma deposition technology. Cathodic arc plasma deposition is a relatively new thin film deposition technology, similar to ion deposition technology in many respects. Its advantage is that it has a high ionization rate in the emitted particle stream, and these ionized ions have a high kinetic energy (40-100eV). Cathodic arc plasma deposition embodies many advantages of ion beam deposition, such as enhanced adhesion, increased density of states, and high reaction rate for compound film formation. Cathodic arc plasma deposition has its unique advantages, such as deposition on substrates with more complex shapes, high deposition rate, good coating uniformity, lower substrate temperature, and easy preparation of ideal compounds or alloy chemical ratios.
The evaporation of the cathode material through the evaporation process is attributed to the high current density, and the resulting vapor is composed of electrons, ions, central gas atoms and particles. At the cathodic arc point, the material is almost 100% ionized, with ions emitted almost perpendicular to the cathode surface. When high-energy chromium ions meet nitrogen, they will immediately react and become gaseous chromium nitride molecules.
Application 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 cutting tools. In addition, the applications of chromium nitride include:
High temperature applications
Sliding wear application
Of precision parts
Wear resistance eliminates wear, fretting, micro welding, clamping and adhesion wear
Enhanced corrosion resistance, but not completely sealed parts
Low friction
Can accommodate sharp edges
Small size effect, very suitable for small tolerance parts
The basic material physics of CrN has recently been debated in well-known scientific journals (such as "Nature Materials") due to its good properties. In particular, quantum mechanical calculations of the electronic structure of compounds have demonstrated the importance of magnetism in low and high temperature phases.
