PDC diamond is a unique material that, as a representative of super-hard materials, exhibits exceptional performance in the fields of engineering materials and new functional materials. From a professional perspective, PDC diamond not only has hardness and wear resistance close to that of diamond single crystals but also possesses superior anisotropy and impact resistance comparable to hard alloys. This makes it widely applicable in various fields.
The production process of PDC diamond is unique and complex. It is usually made from graphite through a directional blasting method. This method uses the shock waves from high-explosive blasting to accelerate metal foils that collide with graphite sheets, converting the graphite into PDC diamond. This unique production method gives PDC diamond its unique crystal structure and properties.
As one of the most common fine abrasive powder, PDC diamond exhibits excellent performance. Its hardness reaches about 10000HV, making it the hardest material among man-made substances in the world, much harder than hard alloys and engineering ceramics. Due to its excellent wear resistance, PDC diamond performs outstandingly in cutting processes, reducing cutting force and cutting temperature, improving tool durability and cutting rates, and achieving good machining surfaces.
PDC diamond also has anisotropy, meaning its properties vary in different directions. This characteristic provides greater flexibility in design and processing, allowing customization and optimization according to specific needs. Additionally, compared to single-crystal diamond, PDC diamond can be directly synthesized or processed into specific regular shapes, and new product performance can be predicted, making it suitable for specific applications.
In terms of applications, PDC diamond is widely used in oil and gas drilling, coal geology exploration, mechanical processing, and other fields. In oil drilling tools, the high hardness and wear resistance of PDC diamond enable drill bits to penetrate rock layers more effectively, improving drilling efficiency. In mechanical processing, PDC diamond tools have become an essential means in modern cutting processes, capable of achieving high-speed cutting, highly stable processing, ultra-precise mirror finishing, as well as dry cutting and clean processing.
Besides the above applications, PDC diamond also plays an important role in mining, wire drawing dies, and wear-resistant components. In mining, the high hardness and wear resistance of PDC diamond enable mining tools to break and excavate ores more effectively. In the wire drawing die field, the high hardness and wear resistance of PDC diamond allow molds to withstand greater pulling and friction forces, extending their service life.
