The PDC (Polycrystalline Diamond Compact) Diamond Composite is a super-hard composite material made of diamond micropowder and cemented carbide matrix sintered under high temperature and high pressure. This material combines the high hardness, wear resistance and thermal conductivity of diamond with the strength and toughness of cemented carbide matrix, and is widely used in oil and gas drilling, geological exploration, coal mining and machining, etc., with outstanding performance.
Characteristics of PDC diamond composite sheet
High hardness
The hardness of PDC is close to or reaches the hardness of natural diamond, which is much higher than other hard materials. This enables PDC to easily cope with high hardness cutting and drilling tasks, especially when dealing with hard rock or other high hardness materials.
High Wear Resistance
Due to the high hardness and wear resistance of diamond, PDC diamond composite blades are able to maintain sharp cutting edges over long periods of time. This not only reduces wear and tear, but also reduces the frequency of changing tools or bits, which in turn improves work efficiency and economic benefits.
Good thermal conductivity
Diamond has excellent thermal conductivity, which helps to dissipate heat quickly during the cutting or drilling process. Good thermal conductivity can effectively prevent thermal damage to tools and workpieces at high temperatures, thus extending tool life and improving machining quality.
High strength and toughness
The cemented carbide matrix provides the PDC with the necessary strength and toughness to withstand high intensity shock and vibration. This characteristic is especially important in complex drilling environments, ensuring tool stability and reliability.
Long Life
Due to the high hardness, high wear resistance, good thermal conductivity and the support of the cemented carbide matrix, PDC diamond composites typically have a long service life. This not only reduces production costs, but also minimizes downtime, thus increasing overall productivity.
Areas of Application
PDC diamond composite blades are widely used in a variety of industrial applications due to their excellent performance, especially in the following areas:
1. Oil and gas drilling
PDC drill bits perform well under high temperature and high pressure conditions and are suitable for drilling deep and ultra-deep wells. Modern PDC bits combine advanced design and optimized cutting structures, enabling them to maintain efficient drilling speeds and longer service life in extreme environments, reducing replacement frequency and non-productive time. In addition, PDC technology continues to evolve, making it adaptable to different types of formations such as hard rock, sandstone and shale.
2. Geological exploration
In geological exploration, the high abrasion and impact resistance of PDC drill bits keeps them operating efficiently when exploring complex geological environments. As the depth of exploration increases, PDC drill bits are able to maintain stable performance under high stress and high temperature conditions. The latest PDC bit design also supports faster drilling speeds and more accurate geological data collection, which is essential for the effective evaluation and extraction of mineral resources.
3. Coal Mining
In coal mining, PDC bits not only effectively penetrate hard coal seams, but also cope with hard rock and other impurities trapped in the seams. Its excellent impact resistance and long life substantially reduce downtime and improve mining efficiency. In addition, the advancement of PDC technology enables it to maintain stable performance in high gas and high temperature environments, which guarantees the safety of miners.
Machining
In the field of machining, PDC diamond composite chip tools are especially suitable for precision machining of high hardness materials, such as ceramics, glass and cemented carbide. Due to its high wear resistance and high thermal conductivity, PDC tools are able to keep the cutting edge sharp at high rotational speeds, ensuring the finish and dimensional accuracy of the machined surface. At the same time, the long life and low wear of PDC tools reduces the frequency of tool changes, significantly improving productivity and product quality.
