摘要： The invention concerns a composite body consisting of a hard metal, cermet or ceramic substrate body and at least one layer of a mechanically resistant material, a ceramic substance, a diamond-like layer, amorphous carbon and/or hexagonal boron nitride. The invention also concerns a method of producing this composite body, wherein, when the green compact has been dewaxed, with its pores still open and whilst it continues to be heated as from a temperature of between 600° C. and 1100° C., it is acted upon by sublimable solids and/or reaction gases which are necessary for coating purposes. The temperature of the green compact is then further increased and the latter is fully compressed by sintering, before one or more layers of the above-mentioned type is/are applied.

摘要： Disclosed are a composite body and the production and the use thereof. It consists of a substrate body with a single- or multilayer coating, containing either Ti, Zr, Hf, V, Nb carbides, nitrides, carbonitrides and/or Ta and/or Al2O3 or ZrO2. In order to improve the characteristics of wear from chip removal or another form of abrasion, the invention suggests that a layer of Zr, Hf, V, Nb, Ta or Cr carbonitride be precipitated either directly upon a layer of Al2O3— or ZrO2— or upon a thin intermediate layer of ZrC or ZrN up to 0,5 &mgr;m, or upon a TiN layer up to 0.1 &mgr;m, or indirectly upon a layer of Al2O3— or ZrO2—.

摘要： A hard metal or cermet body, especially as a cutting insert, has a WC content in the hard phase making up at least 10% and at most 96% thereof and three layers or zones between the interior of the body and the surface formed by the heat treatment to which the sinterable body is subjected. In the outermost layer hard material with limited binder content can be formed underlain by an intermediate layer of a substantially pure WC--Co composition, the innermost layer having a tungsten content falling to the value in the body interior and a binder phase and Group IVa and Group Va metal which increased progressively to the levels in the body interior.
