Chromium carbide powder Introduction

2016-06-02

Chromium carbide powder Extreme hardness and excellent surface finish. They are usually formed by standard P/M techniques,Chemical formula Cr3C2,Molecular weight 180.02,Carbon content 13.344%,Density 6.68 g/cm3, Melting point 1890ºC,Boiling point:3800ºC.Chromium carbide is gray powder with rhombic system structure,which is undissoluble in water and resistant to acid and alkali .It is high melting-point inorganic material with wear resistance,corrosion resistance and resistance to oxidation at elevated temperature(1000~ 1100ºC).

Application：

a)Structural applications include bearings, seals, valve seats and orifices. Corrosion resistance makes them candidates for chemical equipment service.

b) Chromium carbide is used as a thermal spray material for protecting the underlying metal surface, and as an additive to corrosion-resistant and wear-resistant materials. It is used as a fine-crystal phase in other sintered carbides, where, like the vanadium carbide, it inhibits growth of submicrometre grains during pressing and sintering.

c) Chromium carbide applications are particularly effective where sliding abrasion is present. For example, in chutes, liners, hoppers, flasks, bucket kits, skid plates, apron feeders, cyclones, fan blades, etc.
