European Science, 2024•desymp.promonograph.org… A new generation of thermostable PDC cutters has also been proposed [14], which builds
upon the existing thermostable structures by complementing the planar leached layer with a
non-planar diamond-solid interface (Fig. 4). … The incorporation of additional thermostable
material in the cutting edge area of the PDC further delays the onset of wear compared to
first-generation thermostable PDCs. During the wear of the cutting edge, a "double-edge" cutting
structure is formed. This increases productivity as both edges are able to cut the rock. … By …

Abstract
Polycrystalline diamond, with its high hardness and wear resistance as well as other excellent properties such as low friction, high thermal conductivity, high corrosion resistance and low electrical conductivity, plays a leading role in the selection of
