| Abstract: | In this paper, a type of spherical Cr3C2-25% NiCr powders were prepared by agglomerated and sintered with ultrafine chromium carbide. Abrasion resistant coating was prepared using these powders by High Velocity Oxygen-Fuel spraying（HVOF）. The chemical compounds and surface of Ultrafine CraC2-25%NiCr powders were analyzed. The influence of ultrafine Cr3C2-25%NiCr powders to coating is studied by compared experiments of bonding strength and hardness of the coating. |
