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.
