Brief Description of Chromium Carbide Cr3C2

Chromium carbide is a ceramic compound that exists in several different chemical compositions: Cr3C2, Cr7C3,and Cr23C6. At standard conditions it exists as a gray solid.
It is extremely hard and corrosion resistant.
It is also a refractory compound, which means that it retains its strength at high temperatures as well.
These properties make useful as an additive to metal alloys. When chromium carbide crystals are integrated into the surface of a metal it improves the wear resistance and corrosion resistance of the metal, and maintains these properties at elevated temperatures.
Cr3C2 powder is mixed with solid nickel-chromium. This mixture is then heated to very high temperatures and sprayed onto the object being coated where it forms a protective layer. This layer is essentially its own metal matrix composite, consisting of hard ceramic Cr3C2 particles embedded in a nickel-chromium matrix.
Cr3C2 prevents large grains from forming in the composite, which results in a fine-grained structure of superior toughness.

Application of Chromium Carbide Cr3C2
1. Used as high temperature resistant and wear-resistant surface materials
2. Used for welding and flux cored wire 
3. Chromium carbide is useful in the surface treatment of metal components.
4. Chromium carbide is used to coat the surface of another metal in a technique known as thermal spraying.
5. Chromium carbide is used as an additive in cutting tools in order to improve toughness by preventing the growth of large grains.
Properties of Chromium Carbide Cr3C2
There are three different crystal structures for chromium carbide corresponding to the three different chemical compositions. Cr23C6 has a cubic crystal structure and a Vickers hardness of 976 kg/mm2. Cr7C3 has a hexagonal crystal structure and a microhardness of 1336 kg/mm2.
Cr3C2 is the most durable of the three compositions, and has an orthorhombic crystal structure with a microhardness of 2280 kg/mm2. For this reason Cr3C2 is the primary form of chromium carbide used in surface treatment.
