Polycrystalline diamond compacts (PDC), which are composed of diamond and WC/Co substrate, and synthesized at the ultra-high pressure and high temperature conditions, are widely applied as the tooth of oil and gas drilling bit. 


The surface of the polycrystalline diamond compact (PDC cutter) is polycrystalline diamond sintered from powders of different diamond sizes, which has a high hardness, high wear resistance, great thermal stability, and a long working life. 


DIAMONDWK PDC cutters are widely used in oil and gas drilling.

WKK

Fine thermal stability and wear resistance, stronger impact resistance.


WKS

Certain impact force, enhance wear resistance and extand working life.


WKP

Improved impact force made the cutting force increased


WKY

Keep impact and heat resistance, with better wear resistance.






EMS and SEM Test

Scanning electron microscopy was used to detect the difference in microstructure and element composition distribution of the synthesized polycrystalline diamond composite sheets. In order to check whether the binder is mixed evenly, the size of the particles, etc.

VTL Test

During the test, the PDC tooth is fixed to the VTL lathe at a certain angle, and a rock sample (usually No. 8 granite) is placed next to the PDC tooth and then the rock sample is rotated around the axis of the lathe at a certain speed, and the PDC tooth is cut to some extent. Deeply cut into the rock sample to test the life of the diamond composite sheet. The commonly used testing equipment is the vertical CNC lathe.
