High wear resistance Tungsten Carbide Tools CO 8% for Artificial Diamond Synthesis
 
 
Description:
 
Cemented carbide anvils are forged, pressed and hip sintered by powder metallurgy technique. Carbide anvils are key components of EHV and high temperature apparatus which can synthesize artificial diamonds.
 
Due to its high strength, wear resistance, excellent toughness and thermal stability, tungsten carbide becomes an optimal material for this application. Since the anvil is mounted on a large pad cubic of 6 facet piston top, cavity can reach a state of 10 to 20 GPa and 1500 when six anvils are drove together by cylinder which forms a closed environment. Thus tungsten carbide anvil is working under a supercritical condition, suffering stress, tensile stress and shear stress at the same time.
 
Some important properties of 6 facet tungsten carbide anvils. 
 

1. Bending strength.
 At high temperature, the bending strength of carbide anvil will decrease. Cooled by water, we can prolong its service life. The bending strength is also related to its structure.
 
2. Compressive strength.
 The compressive strength is the most important indicator of 6 facet cemented carbide anvils.
 
3. Impact toughness.
 The impact toughness is highly related to the content of free carbon. Low impact toughness may lead to fracture.
 
4. Hardness.
 The hardness of 6 facet tungsten carbide anvils indicates the compression resistance. It is affected by cobalt content, WC particle size and temperature.
