  • Patent number: 6528171
    Abstract: 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.

  • Patent number: 6521349
    Abstract: The invention relates to a tool, especially a cutting insert for cutting metallic materials, consisting of a hard metal, cermet, ceramic or steel base body and at least one coating deposited thereon. This single coating or in the event that there are several layers, the outer layer or the layer below the outer layer, consists essentially of molybdenum sulphide. The invention also relates to a method for producing the molybdenum sulphide coating by chemical vapour deposition. According to the invention, the molybdenum sulphide coating contains a mixture of the sulphide phases MoS2 and Mo2S3 with an essentially random orientation (isotropic orientation) of the phase crystals. The coating is applied by means of a chemical vapour deposition procedure.

  • Patent number: 6350510
    Abstract: The invention pertains to a processing insert comprised of a body with a hard metal or ceramic substrate and with a multilayer coating and the manufacture of same. In order to have a highly fracture-tough insert with a relatively thick coating, it is suggested that an external layer (protective layer) be applied according to the CVD process, said layer being either a monophase or multiphase layer of Zr-based or Hf-based carbide nitride or carbonitride, and presenting internal compressive stresses. The layer(s) underlying the external layer, also applied according to the CVD process, also present(s), without any exception, internal compressive stresses, while at least one of them, maybe the only one laying under the protective layer is made of TiN, TiC and/or TiCN. The coating is applied according to a continuous CVD process at temperatures of 900° C. to 1100° C. and involves a specific modification of the gas compounds.

  • Patent number: 5093151
    Abstract: A plasma-activated CVD process provides improved adhesion of the coated surface layers and employs, as the plasma exciting source, a pulsed direct voltage and a residual direct voltage which remains during the pulse intervals. The residual direct voltage is equal to or greater than the lowest ionization potential of the gases participating in the CVD process, but is no more than 50% of the maximum value of the pulsed direct voltage. The total thickness of the layer(s) does not exceed 30 .mu.m and the temperature of the basic tool body during the coating process is reduced, compared to prior art plasma CVD processes, and ranges from between 400.degree. to 800.degree. C., and is preferably kept below 600.degree. C.
