Development of a novel triple-layer polycrystalline diamond compact

The objective of this research was to obtain a triple layer Polycrystalline Diamond Compact (PDC) via the High-pressure High-temperature (HPHT) sintering method. A thin layer of WC with 20 wt.% Nb/Ni was used as an interface between the top layer of Polycrystalline Diamond (PCD) with pure Nb binder...
