Brief Description Of PDC Cutter
Polycrystalline diamond compact (PDC) cutter is a super-hard composite material that is made of fine diamond powder as raw material, tungsten carbide as the matrix, and sintered under high temperature and high pressure through a specific synthesis process. The composite cutter has the advantages of high diamond hardness, good wear resistance and strong impact resistance of tungsten carbide. It has been expanded from the use of deep well drilling to various fields such as mineral deposit exploration and mechanical processing. Wear resistance, as an important characteristic of the use of PDC, is generally characterized by the parameter of wear ratio. PDC manufacturers are trying to improve their wear resistance as much as possible, but due to many factors affecting the wear resistance of PDC, and they restrict each other, so there are still some problems to further improve the wear resistance of PDC.
The polycrystalline diamond composite cutter combines the extremely high wear resistance of polycrystalline diamond and the high impact resistance of cemented carbide. The edge of the diamond layer is sharp and self-sharpening, which can always keep the cutting edge sharp, so it is very suitable for the exploration of soft formations to medium-hard formations in petroleum and geological drilling, and the effect is very good. The diamond contents in the polycrystalline diamond composite cutter is as high as 99%, so the diamond layer has extremely high hardness and excellent wear resistance. Its Rockwell hardness is 6.5104~7.0104MPa, or even higher. The tungsten carbide matrix overcomes the shortcomings of the hard and brittle polycrystalline diamond, and greatly improves the overall impact toughness of the product. The easy weldability of tungsten carbide solves the problem that polycrystalline diamond is difficult to combine with other materials through welding methods, and can make the polycrystalline diamond composite cutter vertical inlaid and welded on the drill bit.
