Drill Bits TRIZ Cases
- Gradient PDC Cutter Structure for Thermal Stress Relief
A smooth diamond-WC compositional gradient cuts CTE mismatch in PDC cutters, improving thermal stability and service life.
- Chromium WC-Co Rock Drill Insert With Surface Hardness Gradient
A chromium-tuned WC-Co insert uses a surface-to-bulk hardness gradient and compressive stresses to resist wear, corrosion, and breakage.
- Resonant Transformer Circuit for Downhole Electrocrushing Pulses
Resonant tank circuits convert low-voltage power into downhole high-voltage pulses, cutting energy loss while fracturing rock more efficiently.
- Resonant Transformer Circuit for Downhole Rock-Fracture Pulses
Electrical resonance and coupled tank circuits generate high-voltage pulses near the drill bit, cutting transmission loss in downhole electrocrushing.
