Cemented carbide PDC substrate is a composite material composed of diamond and cemented carbide matrix with high hardness and good wear resistance, which is widely used in oil drilling, geological exploration, on coalfield drilling bits and in machining tools and other industries.
Drilling tungsten carbide PDC substrate: suitable for soft to medium-hard geological drilling, with high impact toughness and thermal stability, heat-resistant temperature up to 750℃(two minutes), these products are available in flat and a variety of groove surface combination type, and according to user needs to design the groove, grinding, polishing, chamfering, etc., can provide special shape products.
Mechanical tool class carbide PDC substrate: suitable for cutting high hardness alloy, wood, ceramics and other non-metal, non-ferrous metal and other metal cutting and processing, with high hardness and wear resistance, high cutting accuracy, at the same time, according to user needs, the product can be processed into rectangular, triangular, fan-shaped and other shapes, can be used to make wear-resistant devices, drill bits, drill teeth (with spherical shape, conical), etc.
Cemented carbide PDC substrate features.
1.By introducing international technology and strengthening the cultivation of our own technology development force, Jetvision adopts new high efficiency catalyst and new technology to produce diamond composite chips with various tooth structures
2.The interface bonding is firm and uniform.
3.With high wear resistance, thermal stability and strong impact toughness, etc.
The current development direction of tungsten carbide PDC substrate mainly has.
1.The polycrystalline diamond layer is thickening continuously, from the initial less than 1mm to the current 2-4mm, the life of the product is also improved.
2.The carbide grain is getting finer and finer, and the comprehensive performance of wear resistance and impact resistance is improved.
3.Improve the thermal stability by optimizing the process or de-Co, increasing the heat-resistant layer and other processes.
4.Optimization of interface structure and improvement of interface stress.
5.Increasing the diameter of the product and improving the synthesis efficiency.
6.Improve the sintering effect and reduce the performance difference.
Artificial carbide PDC substrate is super hard material class, this super word is not specific, the range is very wide. Super hard material is the material with high Rockwell hardness (HR), Brinell hardness (HB), Vickers hardness (HV). The general 45# just HR is 30-60, super hard natural diamond. This concept covers a wide range, high hardness steel, high hardness ceramic, artificial diamond and so on can be counted. With the progress of technology, the industry has now developed new diamond composite piece, there are roof type, steel helmet type, bread piece and so on to the following shaped pieces, without affecting the wear ratio greatly improve the impact resistance toughness of diamond composite piece, promote the diamond composite piece technology rose to a new level.
