Abstract
A cutting element (1) for a tool with an electrically conductive track (6) formed at a surface region. The cutting element (1) comprises a HPHT produced polycrystalline diamond body. The conductive track (6) comprises graphite such that the electrically conductive track (6) has an electrical resistance substantially lower than that of the surface region.
Claims16
A cutting element for a tool, the cutting element comprising:
- a high pressure-high temperature polycrystalline diamond body comprising a surface region;
- an electrically conductive track formed at the surface region, the conductive track comprising graphite, wherein the electrically conductive track has an electrical resistance substantially lower than that of the surface region, and wherein the conductive track has a width of at least three times the average diamond grain size.
A cutting element for a tool, the cutting element comprising a high pressure-high temperature polycrystalline diamond body comprising a surface region, and an electrically conductive track formed at the surface region, the conductive track comprising graphite, wherein the electrically conductive track has an electrical resistance substantially lower than that of the surface region, the cutting element made by a method comprising:
- providing a high pressure-high temperature polycrystalline diamond body comprising a surface region;
- forming a conductive track at the surface region, the conductive track comprising graphite, wherein the electrically conductive track has an electrical resistance substantially lower than that of the surface region.
