Synthesis and characterisation of Φ62 mm polycrystalline

1. Introduction. Polycrystalline diamond compact (PDC) is a composite super-hard material sintered by diamond powder and a WC/Co substrate at a pressure of 5–7 GPa and a temperature of 1500–1700 °C [1,2].It not only has the high hardness, wear resistance, and thermal conductivity of diamond but also has the strength and impact toughness of its WC/Co substrate [, , ].

us20150075877a1 - polycrystalline diamond cutting element

US20150075877A1 - Polycrystalline diamond cutting element

A polycrystalline-diamond cutting element for a drill bit of a downhole tool. The cutting element includes a substrate and a diamond table bonded to the substrate. The diamond table includes a diamond filler with at least one leached polycrystalline diamond segment packed therein along at least one working surface thereof. The cutting element may be formed by positioning the diamond table on

Distinctive mechanical properties of nano-polycrystalline

1. Introduction. Graphite directly converts to diamond completely under high pressure and high temperature (HPHT) of more than 15 GPa and 2300 °C, and so single-phase (binderless) nano-polycrystalline diamond (NPD), consisting of fine diamond grains of several tens of nanometers, can be obtained , , .NPD comprises ultra-fine diamond grains with grains bonded directly and solidly to each other
