Abstract:
A tip for a pick tool, comprising a polycrystalline diamond (PCD) structure joined to a substrate body. The PCD structure has a strike surface including an apex opposite a boundary with the substrate body. At least an outer volume of the PCD structure contains filler material between diamond grains, the content of the filler material being more than 5 weight percent of the PCD material in the outer volume. The outer volume is proximate at least an area of the strike surface including the apex, and the thickness of the PCD structure between the apex and the boundary with the substrate body is at least 2.5 mm.
