摘要： The present invention relates to a method of producing a composite rod from a braze material and a sheet of material comprising cermet. The method comprises scoring a surface of the sheet to produce at least one line of localised stress and subsequently causing the sheet to break along the line of localised stress, thereby to produce a plurality of cermet chunks. The cermet chunks can be combined with the braze material to produce the composite rod. In a particular embodiment, the sheet of material may be a used cermet cutting tip.

摘要： A hard faced surface comprises a metal substrate. Inserts are attached to the substrate as a covering layer on the substrate. Each insert comprises a thermally stable polycrystalline diamond (TSP) body (or polycrystalline diamond or cubic boron nitride) having a plan section, a contact surface and a flat top surface. A boundary coating on the ultra-hard body renders the body wettable by first braze material. A tungsten carbide cap is brazed with said first braze material to at least the top surface of the TSP block. The inserts are brazed to the substrate in a closely packed side-by-side formation with a second braze material that penetrates the gaps between the inserts and between the contact surface of the bodies and the metal substrate. The tungsten carbide caps of the inserts provide a gauge for the hard faced surface, which caps are ground in a finishing step exposing the caps and providing the hard faced surface with a desired dimension including an amount of the thickness of the caps.

摘要： The present invention relates to inserts for hard facing substrates, and a method for hard facing substrates. An insert according to an embodiment of the present invention may comprise a body of ultra-hard material having a welding node located on a first surface thereof and at least one wire electrically connecting the first surface to a second, opposite, surface. In use, the inserts may be temporarily connected to a substrate by applying a resistance welding electrode to the welding node, thereby causing the wires on the second surface to melt and weld the insert to the substrate. A subsequent brazing step may firmly attach the inserts to the substrate.
