Cemented carbide is a hard material used extensively as cutting tool material, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of "carbide" or "tungsten carbide" in industrial contexts usually refer to these cemented composites.

The invention relates to a tool, especially a cutting insert for cutting metallic materials, which consist of a hard metal, cermet ceramics or steel base, especially of a high speed steel base, and at least one layer deposited thereon. The single layer, or in the case of several layers the outer layer or the layer underneath the outer layer, contains molybdenum sulfide. The aim of the invention is to improve the resistance to wear of the friction-reducing, molybdenum sulfide containing layer even at high pressures. To this end, the molybdenum sulfide containing layer consists of an alternating sequence of two layer that are different from one another. The first layer contains 51 to 100% by weight of metallic molybdenum and the second layer contains 21 to 100% by weight of MoS2 which substantially consists of hexagonal crystals that are at least substantially oriented in a plane parallel to the tool surface.

Polycrystalline diamond abrasive elements
A polycrystalline diamond abrasive element, particularly a cutting element, comprises a table of polycrystalline diamond bonded to a substrate, particularly a cemented carbide substrate, along a non-planar interface. The non-planar interface typically has a cruciform configuration. The polycrystalline diamond has a high wear-resistance, and has a region adjacent the working surface lean in catalysing material and a region rich in catalysing material. The region lean in catalysing material extends to a depth of 40 to 90 microns, which is much shallower than in the prior art. Notwithstanding the shallow region lean in catalysing material, the polycrystalline diamond cutters have a wear resistance, impact strength and cutter life comparable to that of prior art cutter, but requiring only 20% of the treatment times of the prior art cutters.

Biocompatible cemented carbide articles and methods of making the same
InactiveUS20070082229A1Eliminate and minimize toxic effectReduce concentrationSurgeryJewelleryBiocompatibility TestingAlloy
This invention relates to cemented carbide articles that are characterized by substantially improved biocompatibility with human skin, tissue, organs, etc., compared with articles made from conventional cemented carbides. The essential feature of these improved biocompatible cemented carbide articles is a binder-depleted zone at and near the exposed surfaces of the articles. By depleting the binder (which mainly consists of Co and / or Ni, as well as their alloys) at and near the surface, the toxic effects of Co and Ni (known carcinogens), as well as the allergic reactions that these metals can cause when in contact with human skin, are eliminated. By depleting the binder only at and near the surface, the bulk properties of the cemented carbide article are not compromised or altered in any manner. Applications of these binder-depleted cemented carbides could include articles that human skin may experience prolonged exposure to, for example, jewelry articles such as rings, bracelets, bangles, chains, necklaces, pendants, watches, watch cases, watch straps, etc. In addition, the cemented carbides of this invention may be used in applications where the article comes directly in contact with human skin, tissue, organs, etc. such as surgical and other medical instruments, razor blades, etc. Also, other applications could include knives, tools, dies, and other wear components that are used to process and handle, and hence, come into direct contact with materials meant for human consumption and / or ingestion. Examples of such materials include foodstuffs and pharmaceuticals.
