Nano carbonized chromium and ultra-fine chromium carbide powder are prepared by special process. The powder is orthorhombic, a=2.821, b=5.52, c=11.46, relative density 6.68, melting point 1890°C, boiling point 3800°C, The coefficient of thermal expansion is 10.3×10-6/K; the metal chromium (chromium trioxide) and carbon are combined at a high temperature of 1400-1600 ° C. The chromium carbide crystal lattice is positive and negative, the density is 6.613 g/cm 3 , and the melting point is 1895 ° C. , chromium carbide is gray, resistant to acid。
1. It can be used as the abrasion resistance film;
2. It can be used as semiconducting film.
3. Adding Cr3C2 to cemented carbide production not only refines WC grains but also improves the strength and hardness of the alloy and can significantly improve the corrosion resistance of the alloy. It is widely used as an alloy structural material for corrosion resistance in industrial production. Gauge, valve, seal ring, etc. are used in spray welding and surfacing for hard surface solders that require both corrosion resistance and high abrasion resistance; widely used in special steel smelting of stainless steel, heat resistant steel, corrosion resistant steel, alloy steel etc.
