arbide is a high hardness refractory metal carbide (WC, TiC) micron-grade powder as the main ingredient, with cobalt (CO) or Ni (NI), MO (MO) as the binder, in the vacuum furnace or hydrogen reduction furnace sintered in the powder metallurgy products. Ⅳb, ⅴb, ⅵb metal carbide, nitride, boride, etc., because of the hardness and melting point is particularly high, collectively known as cemented carbide. The structure, characteristics and application of the hard gold deposit are illustrated with the emphasis of carbide.
