Carbide is the Material Based on Hard Refractory Metal Compound

Carbide is the material based on hard refractory metal compound (hard phase or the ceramic phase) , with metal binder (metal phase), the powder metallurgy method for producing a high hardness, high wear-resistant pieces of , also known as cermet material.

WC - Co cemented carbide is combined of phase of WC and Co binder phase: WC - TiC - Co cemented carbide is the composition of the WC phase, WC - TiC solid solution phase and Co binder phase; And the WC phase, WC - TiC phase belong to the same lysosomal hard phase, they contribute to the wear resistance of cemented carbide, Co phase play the role of binder the hard phase together, contribute to the toughness of cemented carbide, cemented carbide in general owns its contradiction, ie, good toughness, abrasion resistance is poor; good wear resistance, toughness is poor.
