Polycrystalline Diamond Compact (PDC) is a composite material that combines layers of ultra-hard diamond with a tough tungsten carbide substrate, created using high-temperature and high-pressure technology. This combination gives PDC excellent hardness, wear resistance, and toughness, making it ideal for extreme working conditions and high-speed cutting applications. Compared to single-crystal diamond, PDC offers better thermal stability and is more cost-effective while maintaining superior performance.
PDC is widely used in various industries, including oil and gas drilling, geological exploration, metalworking, and woodworking. It provides efficient cutting tools with extended lifespans, capable of handling materials ranging from hard rock formations to high-strength metals and wood products, ensuring smooth cuts and reduced wear.
What is scanning acoustic microscope?
The Scanning Acoustic Microscope (SAM) plays an indispensable role in inspecting Polycrystalline Diamond Compact (PDC). It not only provides deep insights into the internal structure of the material but also supports the entire process from quality control to research and innovation, ultimately ensuring the high performance and reliability of PDC tools in practical applications.
Working Principle of Scanning Acoustic Microscope
Ultrasound Emission
The Scanning Acoustic Microscope (SAM) uses one or more transducers to send high-frequency ultrasound pulses into the sample.
Ultrasound Interaction
These pulses travel through the sample and interact with its internal structures, causing reflections, refractions, scatterings, and absorptions. Different materials and defects (like cracks or voids) affect the ultrasound waves differently.
Signal Reception
The transducer also receives the ultrasound signals reflected back from inside the sample. Changes in signal strength and phase reveal the internal structure and characteristics of the material.
Imaging
SAM creates images of the sample’s internal structure based on these received signals, showing density differences, defect locations, and interface quality.
