What are the differences between CrN and Cr2N?

The US President recently said the conflict between Russia and Ukraine had driven up the prices of all the world's major food staples, including wheat, corn, barley, oilseeds and edible oils, and that Russia and Ukraine together supplied more than 25% of the world's wheat exports and about 20% of its barley exports. 

To address the food shortage, the Biden administration says it plans to increase the number of counties eligible for insurance for double cropping. Double cropping is when farmers grow two different crops a year on the same field. 

Under Biden's plan, the number of counties eligible for two-season crop insurance would increase by 681, for a total of 1,935. 

The UN has warned that up to 1.7bn people are "highly exposed" to the domino effect of the conflict between Russia and Ukraine on the global food, energy, and financial systems.  The agency says conflict could increase hunger in countries where people are already suffering from malnutrition.

Even countries where food is less scarce are being hit by rising prices. U.S. grocery prices rose 1% in April, compared with a 10.8% increase over the past 12 months, the Labor Department said recently.

According to the White House, global food prices have risen nearly 13 percent since the outbreak of the Russia-Ukraine conflict. 

Besides, affected by the ever-changing international situation, the supply and prices of international bulk chromium nitride are still very uncertain.

What is chromium nitride?
Metal chromium and nitrogen can form metal chromium nitride with different nitrogen content under different conditions. the common nitrides of metal chromium are CrN and Cr2N, which is called chromium nitride. CrN and Cr2N are important metallurgical second phases of heat-resistant alloys, especially for special steels, they can be used as reinforcement additives.
 
What are the differences between CrN and Cr2N?
CrN and Cr2N have different physical, chemical and mechanical properties.
For Cr2N structure, the metal Cr has a closely packed hexagonal structure, and the non-metallic N atoms fill in the interstitial position of the closely packed hexagonal structure; in terms of the CrN structure, the metal Cr is arranged as a face-centered cubic lattice, and N atoms are filled in the octahedral gap of the face-centered cubic lattice to form a simple NaCl structure.
It is generally believed that the comprehensive performance of CrN is higher than that of Cr2N. For example, the acid and alkali corrosion resistance of CrN is obviously higher than that of Cr2N.
 
What is chromium nitride used for?
CrN is used as an anticorrosive coating material for metal forming and plastic forming applications.
CrN is commonly used in medical implants and tools.
CrN is also a valuable ingredient in advanced multi-component coating systems, such as CrAlN, for hard wear-resistant applications on cutting tools.
 
What is chromium nitride coating?
Chromium nitride is an extremely hard and inert film coating, which is mainly used in precision metal parts. Chromium nitride (CrN) has higher temperature resistance than TiN, so it is an ideal choice in high temperature environment. CrN also performs well in corrosive environments and sliding wear applications.
 
Chromium nitride coating properties:
The residual compressive stress is lower than that of TiN. Can be piled up thicker.
It is a dense, continuous coating, unlike hard chromium with microcracks.
Can withstand high temperatures of up to 700°C (1300°F) in the air.
Thin film coatings for environmentally safe physical vapor deposition (PVD) vacuum systems.
It can be used in most metals to provide enhanced surface properties, as well as in some ceramics and plastics.
It has the appearance of metallic silver, but it is a superhard material.
Harder than hard chromium plating, up to Rockwell C grade.
Highly inert, non-corrosive, excellent chemical resistance.
Non-toxic-used in medical and surgical equipment and food processing equipment.
High density, no holes.
Usually 3 microns or. 0001 "thick.
Has a thickness consistent with the surface profile of the part.
Form a good bond with the substrate without blistering, peeling or detritus

The resurgence of the global COVID-19 pandemic and the impact of the Russia-Ukraine conflict continued to cause high volatility in commodity prices. Stubbornly high inflation and rising commodity prices are likely to influence each other and thus push each other higher. The price of the chromium nitride may not decrease significantly in the short term.
