Chromium Carbide (Cr3C2) Micron Chromium Carbide Powder
Manufacturer Supplies, Alloy Spraying Raw Materials
Products Description
- Chromium carbide (Cr3C2) is a gray powder with metallic luster and
orthorhombic crystal system. It has good wear resistance, corrosion
resistance and oxidation resistance in high temperature environment
(1000~1100C). It is a kind of metal ceramic.
- Product Usage
- It is a high melting point material with good wear resistance,
corrosion resistance, and oxidation resistance in high temperature
environments. It can be used as a high temperature resistance, wear
resistance, oxidation resistance, and acid resistance coating. It
is widely used in aircraft engines and petrochemical machinery and
equipment. on, which can greatly extend the life of the machinery.
It is also commonly used as a grain refiner for cemented carbide
and other wear-resistant and corrosion-resistant components.
Cr3C2-based cermets have excellent oxidation resistance at high
temperatures. Can also be used on chromium carbide ceramics.
Coarse-grained chromium carbide is used as a melt-blown material to
form a melt-blown coating on the surface of metal and ceramics,
giving the latter properties such as wear resistance, heat
resistance, and corrosion resistance. It is widely used in aircraft
engines and petrochemical machinery and equipment to greatly
improve mechanical performance. life. Also used for spraying
semiconductor films.
Main uses of chromium carbide
Welding consumables industry
- Chromium carbide prepared from metallic chromium raw materials is
mainly used in wear-resistant welding rods, spray coating and
special stainless steel. When chromium carbide acts on welding
materials, it has the following main advantages:
- (1) Reduce the melting point of the welding rod, which is
beneficial to welding;
- (2) Improve mechanical properties and increase the tensile strength
and shear strength of tin-lead alloy;
- (3) Reduce surface tension and viscosity, increase fluidity and
wettability of liquid solder, etc.

Spraying Industry
- Chromium carbide has a low melting point. Its main characteristics
are that chromium carbide has high hardness at room temperature and
hot hardness. It has good wettability with metals such as Co and
Ni. It has high oxidation resistance and excellent corrosion
resistance among metal carbides. It is a material with excellent
comprehensive properties of resistance to high temperature
oxidation, friction and wear and gas erosion. It is mainly used in
high-temperature resistant coatings, but direct spraying of
chromium carbide coating does not have strong adhesion, so it is
mainly used as the main raw material component for producing
NiCr-Cr3C2 composite powder.
