Chromium carbide Cr3C2 powder CAS 12012-35-0

Overview of chromium carbide Cr3C2 powder:

Chromium carbide is an organic compound with a molecular formula of Cr3C2 and a molecular weight of 180.01.Gray powder,orthorhombic crystal system,a = 2.821,b = 5.52,c = 11.46,melting point 1890°C,boiling point 3800°C.The micro Vickers hardness(load 50 g)is 2700kg/rnrn2,and the thermal expansion coefficient is 10.3×10-6/K.Insoluble in water,resistant to acids and alkalis.It is a high melting point inorganic material with good wear resistance,corrosion resistance and oxidation resistance in high temperature environments(1000-1100 degrees).Chromium carbide is used as a thermal spray material for metal surface protection,and it is also often used as a cemented carbide.Grain refiners and other wear-resistant and corrosion-resistant parts.Chromium carbide-based cermets have excellent oxidation resistance at high temperatures,and the surface only slightly darkens after exposure at 982°C for 5 hours.Under the same conditions,18-8 stainless steel has been severely damaged,Chromium carbide Cr3C2 powder is a very hard refractory ceramic material.It is a fine gray powder,rarely the natural mineral Tongbaishi.Chromium carbide has strong corrosion resistance and high temperature oxidation properties,and its thermal properties are similar to steel.It is an excellent material for many commercial industries.Several different chromium carbide compounds can be formed,each of which has slightly different mechanical properties and applications.Chromium carbide is used as a thermal spray material to protect the surface of the underlying metal,and as an additive for corrosion-resistant and wear-resistant materials.Where there is sliding wear,the application of chromium carbide is particularly effective.

Chromium carbide is produced through a combination of thermite reduction and vacuum furnace at a temperature of 1500°C and above.A mixture of chromium metal,chromium oxide and carbon is prepared and then charged into a vacuum furnace.Reduce the pressure in the furnace and increase the temperature to 1500°C.The carbon reacts with chromium oxide to form chromium metal and carbon monoxide gas,which is discharged into the vacuum pump.Then,the chromium metal combines with the remaining carbon to form chromium carbide.

Chromium oxide,the precise balance between chromium metal and carbon determines the grade of chromium carbide produced.This is strictly controlled to ensure that the product quality is suitable for a strict market such as aerospace.

Chromium carbide Cr3C2 powder application:

What are the uses of chromium carbide Cr3C2 powder?

Chromium carbide Cr3C2 powder is a high melting point material with good wear resistance,corrosion resistance and oxidation resistance in high temperature environments.It is made of hard alloy particles made of nickel-chromium alloy and adopts plasma spraying method,which can be used for high temperature resistance and wear resistance.

1.Oxidation-resistant,oxidation-resistant and acid-resistant coatings are widely used in aircraft engines and petrochemical machinery and equipment,which can greatly increase the service life of the machinery.It is also commonly used as a grain refiner for cemented carbide and other wear-resistant and corrosion-resistant parts.Cermets based on Cr3C2 have excellent oxidation resistance at high temperatures.

2.Used for chromium carbide ceramics. Coarse chromium carbide is used as a melt-blown material to form a melt-blown layer on the surface of metals and ceramics,thereby imparting wear resistance, heat resistance,corrosion resistance and other properties to the ceramic.It is widely used in aircraft engines and petrochemical machinery to greatly extend the service life of the machinery.It is also used for spraying semiconductor films.

3.As a thermal spray material, chromium carbide Cr3C2 powder used to protect the metal surface below.

4.Additives used to manufacture wear-resistant and corrosion-resistant materials.

5.As a coating for seals, bearings and valve seals.

6.As the microcrystalline phase in the cemented carbide(such as vanadium carbide),chromium carbide Cr3C2 powder is used to inhibit the growth of sub-micron grains during the pressing and sintering process.
