Tungsten carbide cladding offers significant advantages for PDC drill bits, enhancing their performance and lifespan in demanding drilling operations.

Forming Process:

Utilizing advanced automated PTA and laser cladding systems, a highly wear-resistant tungsten carbide alloy layer is precisely deposited on the surfaces of PDC (Polycrystalline Diamond Compact) drill bits, enhancing tool life and drilling efficiency in extreme downhole conditions.

Application Range:

Custom cladding available for various PDC drill bit sizes and geometries, including matrix body and steel body designs.

Base Material:

High-strength alloy steel or tool steel used in PDC bit construction.

Cladding Material:

Nickel-based tungsten carbide (Ni-WC) alloy – engineered for extreme hardness, thermal stability, and resistance to abrasion and erosion.

Applications:

Primarily used in oil & gas drilling, geothermal exploration, and mining operations, especially in abrasive formations requiring high durability and extended bit life.
