    摘要： A machining tool comprising at least one diamond-coated functional region having a substrate surface composed of a hard metal or a ceramic material arranged beneath the diamond layer. The substrate surface contains hard material particles on the basis of carbide and/or nitride and/or oxide, which are embedded in a cobalt-containing binding matrix. The diamond layer is directly arranged on the substrate surface without cobalt having been removed by chemical or physical methods in substantial amounts out of the binding matrix of the substrate surface. Such a tool is produced by pre-treating a hard metal substrate surface with a positively charged ion beam, followed by conventional CVD-diamond coating directly onto the ion beam-pre-treated cobalt-containing substrate surface. The ion-underlying atoms thereby largely remain in the substrate. The tools according to the invention have good diamond layer bonding to the substrate and a high wear resistance.

    摘要： A coated tool is provided which is capable of inhibiting occurrence of chipping, peeling-off, or the like of a diamond layer by enhancing fracture resistance, and which has the diamond layer with high wear resistance. The coating tool is, for example, a drill having a diamond layer coated on a surface of a base material. The diamond layer has a first coating layer located close to the base material, and a second coating layer located on the first coating layer. A mean particle size of second diamond particles constituting the second coating layer is smaller than a mean particle size of first diamond particles constituting the first coating layer. The diamond layer contains hydrogen, and a hydrogen content in the second coating layer is larger than a hydrogen content in the first coating layer.

    摘要： A coated cutting tool insert includes a substrate of cemented carbide, cermet, ceramics, steel or cubic boron nitride having deposited thereon a coating having a total thickness of 60 μm, including one or more layers having a wear resistant layer of α-Al2O3 of a thickness of 1 to 45 μm deposited by chemical vapour deposition (CVD). The α-Al2O3 layer includes at least two portions, a first thickness portion and a second thickness portion immediately on top of the first thickness portion. The first thickness portion has an essentially columnar α-Al2O3 grain structure, and at a transition from the first thickness portion to the second thickness portion the grain boundaries of at least 1 out of 25 neighboring grains of the α-Al2O3 grains undergo a directional change into a direction that is essentially perpendicular, 90±45 degrees, to the grain boundaries in the first thickness portion.
