Chromium Nitride Powder

Chromium Nitride (CrN) is gray black powder, stable to water, acid and alkali. Chromium Nitride is not only an excellent additive for steel-making alloy, but also has good physical and mechanical properties, which is better than titanium nitride in wear resistance. Mainly used for wear-resistant coating. It can be used for anti-corrosion metal coating materials and plastic molds, as well as multi-component coating materials.

Preparation

The low carbon ferrochromium is nitrided in a vacuum furnace at 1150℃ to obtain coarse nitrided ferrochromium, which is then treated with sulfuric acid to remove iron impurities. After filtration, washing and drying, chromium nitride is obtained. It can also be prepared by the reaction of ammonia and chromium halide.

Other Trade Names: chromium nitride (Cr₂N), chromium nitride, dichromium nitride, chromic nitrogen(-3) anion

Typical Applications:

Chromium Nitride is often used as film coating. With high hardness and good wear resistance, it is a very important wear-resistant coating. The CrN film prepared by hollow cathode ion plating has two-phase structure of Cr + Cr₂N, with grain size of 20-70 nm and hardness HV 22 GPa. After vacuum annealing, it can be increased to HV 35.4 GPa. Its wear resistance is better than that of CrC film. Cr + Cr₂N or single-phase CrN can be obtained from CrN films by reactive sputtering. The hardness of CrN films is HV 20-25 GPa (the hardness of bulk CrN is HV 11 GPa).
