    摘要： A pick tool comprising a strike member non-moveably attached to a pick body, the strike member comprising a strike structure. The strike structure comprises super-hard material and defines a planar strike surface, the strike surface defining a cutting edge that includes an apex in the plane of the strike surface. The thickness of at least a proximate volume of the strike structure adjacent the cutting edge is at least about 2 millimetres.

    摘要： A pick assembly is provided, comprising a bit assembly and a holder assembly; the bit assembly comprising a bit support body, a fastener mechanism and a deflectable member, cooperatively configured such the deflectable member can be deflected responsive to the progressive coupling of the bit support body to the fastener mechanism. The holder assembly comprises a holder body and is configured for accommodating and retaining the bit assembly by interference means. The holder assembly and bit assembly are cooperatively configured such that the retention of the bit assembly by the holder assembly by interference means can be progressively increased responsive to the progressive coupling of the bit support body with the fastener mechanism when the bit assembly is accommodated by the holder assembly, operative to prevent substantial movement of the bit support body relative to the holder body in use.

    摘要： 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 per cent 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.

    摘要： A method of processing a composite body comprising a super-hard structure and refractory metal material exposed proximate a boundary of the composite body, the refractory metal material comprising refractory metal. The method includes providing a basic corrosive agent, heating the corrosive agent to at least its melting point, contacting the composite body with the corrosive agent in the molten state and treating the composite body with the corrosive agent for a period of time to remove refractory metal material from the composite body.
