Polycrystalline Diamond Compact
Definition and structure:
PDC is a composite material formed by sintering artificial diamond powder and cemented carbide substrate under high temperature and high pressure conditions.
It usually consists of two parts, the upper layer is a diamond layer with extremely high hardness and wear resistance; the lower layer is a cemented carbide layer,
which provides support and connection.
Performance characteristics:
High hardness: The hardness of PDC is second only to natural diamond, and it can effectively cut and grind various hard materials.
High wear resistance: During cutting and drilling, PDC has a long service life, reducing the frequency and cost of tool replacement.
Good thermal stability: It can work at higher temperatures and is not easily damaged by high temperatures.
Customizability: PDC of different specifications and shapes can be designed and manufactured according to different application requirements.
Application areas:
Oil and gas drilling: PDC drill bits are widely used in oil and gas drilling, which can improve drilling efficiency and reduce drilling costs. Compared with traditional roller bits, PDC drill bits have higher drilling speeds and longer service life.
Geological exploration: Used for drilling operations in mineral resource exploration, it can obtain more accurate geological information.
Mining: In mining, PDC cutters can be used to cut and crush rocks to improve mining efficiency.
Engineering construction: In fields such as trenchless engineering and foundation engineering, PDC tools can be used for drilling, cutting and other operations.
Bearings: The high wear resistance and load-bearing capacity of PDC bearings make them an important component in mining equipment, such as crushers, vibrating screens, conveyors, etc.
PDC bearings can withstand the wear of solid particles, rock debris, etc. in the drilling fluid and maintain good working performance.
The hardness of PDC material is second only to natural diamond, which makes PDC bearings have strong anti-deformation and load-bearing capacity, and can withstand large loads.
