Product Name: Chromium Carbide Cr3C2 Powder

Chromium Carbide Cr3C2 Powder APPLICATION FIELDS

Chromium Carbide Cr3C2 Powder 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 use 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.

Chromium Carbide Cr3C2 Application:

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.

Chromium Carbide Cr3C2 Properties:

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.

Product Name: Ferrovanadium Nitride Powder

Ferrovanadium Nitride Powder Description: 

Ferrovanadium Nitride (Vanadium-Nitrogen alloy) is a composition ferrovanadium nitride.

Ferrovanadium nitride is proposed for joint nitrogen and vanadium steel doping.

Ferrovanadium Nitride (Vanadium-Nitrogen Alloy) is a new type of alloy additive,

It can substitute Ferro Vanadium used in the production of Micro alloying-steel.

Ferrovanadium Nitride Powder Application:

1. FeVN alloy powder can be used for structural steel, tool steel, pipeline steel, steel, and cast iron.
2. It is used for nitrogen-containing steel melting: high- strength low-alloy steel (HSLA), rail steel, quick cutting steel, etc.

4. Ferrovanadium Nitride adding to the steel can increase the strength, tough, tactility, anti-thermal fatigue, etc.
5. It also can make the steel be able to fulfill solderability to attain the same strength, adding Ferrovanadium Nitride could save 30-40% of Vanadium, thereby saving the cost.

Ferrovanadium Nitride Powder Advantages:

1. Low melting point, high-density products, under the condition of the same production, vanadium and nitrogen yield is higher than similar products.
2. Low nitrogen vanadium than more reasonable, high strengthening ability.
3. Stable high product purity, ingredients, production has smaller fluctuation, the mechanical performance of steel performance has higher reliability.

Tungsten Carbide Powder

Product Name: Tungsten Carbide Powder

Brief Description of WC Tungsten Carbide Powder

Tungsten carbide powder (chemical formula: WC ) is a chemical compound (specifically, a carbide ) containing equal parts of tungsten and carbon atoms.

In its most basic form, tungsten carbide is a fine Gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.

Physical Properties of WC Tungsten Carbide Powder

Tungsten carbide has a high melting point at 2,870 °C (5,200 °F), a boiling point of 6,000 °C (10,830 °F) when under a pressure equivalent to 1 standard atmosphere (100 kPa), the thermal conductivity of 110 W·m−1·K−1, and a coefficient of thermal expansion of 5.5 µm·m−1·K−1.

Tungsten carbide is extremely hard, ranking about 9 on Mohs scale, and with a Vickers number of around 2600.

It has Young’s modulus of approximately 530–700 GPa, a bulk modulus of 630–655 GPa, and a shear modulus of 274 GPa.

It has an ultimate tensile strength of 344 MPa, the ultimate compression strength of about 2.7 GPa and a Poisson’s ratio of 0.31.

Chemical Properties of WC Tungsten Carbide Powder

There are two well-characterized compounds of tungsten and carbon, WC and tungsten semi abide, W2C.

Both compounds may be present in coatings and the proportions can depend on the coating method.

At high temperatures, WC decomposes to tungsten and carbon and this can occur during high-temperature thermal spray, e.g., in high-velocity oxygen fuel (HVOF) and high energy plasma (HEP) methods.

Application of WC Tungsten Carbide Powder 

1 Used for Producing high capability nano-crystalline or superfine horniness alloy, hard-face abrasion-resistant spraying and petrochemical cracking catalyst;

2. Used for chipless forming tools; Cutting tools; Mining tolls; Nano-composites (for enhanced hardness, strength, and wear resistance);
3. Used for erosion-resistant coatings; wear-resistance coatings; Corrosion-resistant coatings; Wear-resistant parts
4. To produce hard carbide.
