◆ Carbide inserts are fixed in a nickel-based binder phase containing cast WC particles, improving the product's corrosion resistance;
◆ Perfectly combines the wear resistance of carbide with the toughness of steel;
◆ The edges of the flow channels are specially reinforced to enhance the bonding strength and toughness, preventing brittle chipping and spalling of the hardened layer;
◆ Low-temperature preparation process preserves the excellent mechanical properties of heat-treated steel;
◆ Non-stick threads;
◆ High bonding strength between the hard surface layer and the steel substrate;
◆ Specially designed carbide blocks possess high wear resistance and fracture toughness;
◆ Excellent impact and erosion resistance;
◆ High load capacity;
◆ Longer service life than traditional sintering processes and coated products;
◆ Reusable;
◆ Lower cost per drilling operation;
◆ Maintains consistently excellent performance in any harsh working conditions;
◆ Lower replacement frequency and reduced inventory requirements;
◆ Provides your drilling tools with superior reliability and high competitiveness.
Operating conditions:
Location: Texas, USA
Product: Lower radial bearing
Rotational speed: 400-450 r/min
Slurry concentration: 5-6%
Problems:
* Large amounts of cemented carbide blocks are peeling off.
* Numerous cracks on the cemented carbide surface.
* Threads are seizing, making disassembly difficult.
* Base material is deformed, rendering the product unusable. * Microcracks on the cemented carbide surface.
* No cemented carbide block peeling.
* Threads are not seizing, disassembly is smooth.
* Still reusable.
Solution:
◆ The cemented carbide inserts are fixed in a nickel-based binder phase containing cast WC particles.
◆ This perfectly combines the wear resistance of cemented carbide with the toughness of steel.
