CVD Diamond Tool Outperforms PCD Tool by 50%-560% in Tool Life
Share:
CVD is 100% pure diamond with fine grains in micron sizes, its grain boundaries are 100% diamond as well.
PCD is ~90% diamond powers sintered with binding metal powders such as cobalt & nickel. As a result, PCD tools usually fail from binding phase since they are less strong than diamond.
CVD-diamond tool also offers great cutting edge integrity without any micro damage which happens often in PCD tool. As a result, CVD diamond tools are stronger, harder, and last longer than PCD tool by 50% to 560% depending upon applications. It has the highest wear resistance and high thermal conductivity (HSC and HPC), and high toughness.
