1. The basic characteristics of chromium carbide powder:
Chromium carbide is a dark gray powder，made of metallic chromium and carbon by vacuum carbonization. The formula is Cr3C2 (carbon theoretical weight percentage of 13.4%), orthorhombic crystal system structure.
Chromium carbide ｉｓ insoluble in water, acid and alkali resistant.
Chromium carbide is a kind of refractory, corrosion-resistant and oxidation-resistant inorganic material with high melting point under high temperature environment (1000-1100 ℃). It is widely used as thermal spraying material for metal surface protection.
Chromium carbide is also commonly used as a carbide grain refiner and other wear-resistant, corrosion-resistant components.
Carbide-based cermets have excellent oxidation resistance at high temperatures. After exposure to 982 ° C for 5 hours, the surface is only slightly dimmed. In the same conditions, 18-8 stainless steel has been significantly damaged, WC-6Co alloy is completely oxidized.
2. The main purpose of chromium carbide powder:
Chromium carbide for special welding materialｓｃan be used for special welding materials manufacturing, surfacing series of electrodes, flux cored wire.
Chromium carbide
The addition of Cr3C2 in the cemented carbide production not only can refine the WC grains, but also improve the strength and hardness of the alloy and significantly improve the corrosion resistance of the alloy.
Chromium carbide is used for thermal spraying powder material
To Cr3C2-based NiCr superalloy alloy powder after processing, using plasma spraying, can be made of high wear resistance, corrosion resistance, high temperature coating, should be widely in the fan blades, bad seal, the boiler "four tubes" and so on.
Chromium carbide for arc spraying wire and submerged arc welding of tubular wire
Arc spraying wire added Cr3C2 material, improved high temperature wear resistance, used in the boiler "four tubes" repair and prevention, metallurgical industry, iron cloth grate slot wear liner, power plant mill roller due to the use of Cr3C2 added Tubular wire surfacing prevention and protection, greatly improving the service life.
