    摘要： A plain bearing overlay (3) of which exhibits properties which are markedly improved with regard to wear resistance in comparison with overlays applied by electroplating and conventional electron beam vapor deposition methods. The surface of the overlay (3) comprises round raised portions (4) and depressed portions (6), wherein, in relation to the horizontal section plane (7), the raised portions (4) cover a proportion of the surface area amounting to 30% to 50%, based on the entire surface area of the plain bearing, the section plane (7) being at a height at which the total proportion of the surface area consisting of the raised portions (4), and obtained in vertical section, is equal to the total corresponding proportion consisting of the depressed portions (6). The round raised portions exhibit a diameter D of 3 to 8 &mgr;m, in plan view, wherein, in the case of raised portions (4) and depressed portions (6) which in plan view are not circular, this value relates to the maximum diameter. The surface exhibits a roughness of Rz=3 to 7 &mgr;m. The method of producing such plain bearings is based on electron beam vapor deposition, wherein a backing member with a roughness of Rz23 2 &mgr;m is used and vapor deposition of the overlay is effected at a pressure

    摘要： Vacuum coated compound body and a process for its production. Such compound bodies, when coated in a known manner, have a carrier of a metal or of an alloy, a layer that is thermally, mechanically and chemically unstable, with their surface showing cracks and being partially porous. These shortcomings are overcome via an improved eco-friendly vacuum deposition process wherein at least one layer of a material having an outer layer is of Al.sub.2 O.sub.3, is applied to the metal or alloy carrier at a maximum of 700.degree. C., with this layer being completely crystalline and comprised of an .alpha.Al.sub.2 O.sub.3 phase and possibly of a .gamma.Al.sub.2 O.sub.3 phase with a (440) texture, having a compressive stress of at least 1 Gpa and a hardness of at least 20 Gpa, with the Al.sub.2 O.sub.3 layer being deposited via reactive magnetron sputtering, wherein the magnetrons are pulse powered, the pulse frequency lies between 20 and 100 Khz, and the deposition rate is at least 1 nm/s, with the compound bodies being utilized for cutting treatments, particularly as drills, milling cutters, reamers, broaches or saw blades.

    摘要： The present invention describes a coated cutting tool for metal machining. The coating is formed by one or more layers of refractory compounds of which at least one layer of fine-grained, crystalline &ggr;-phase alumina, Al2O3, with a grainsize less than 0.1 &mgr;m. The Al2O3 layer is deposited with a bipolar pulsed DMS technique (Dual Magnetron Sputtering) at substrate temperatures in the range 450° C. to 700° C. preferably 550° C. to 650° C., depending on the particular material of the tool body to be coated. Identification of the &ggr;-phase alumina is made by X-ray diffraction. Reflexes from the (400) and (440) planes occurring at the 2&thgr;0- angles 45.8 and 66.8 degrees when using CuK&agr; radiation identify the &ggr;-phase Al2O3. The alumina layer is also very strongly textured in the [440]-direction. The Al2O3 layer is virtually free of cracks and halogen impurities. Furthermore, the Al2O3 layer gives the cutting edge of the tool an extremely smooth surface finish.

    摘要： The present invention relates to a process for producing a coated cutting tool consisting of a coating and a substrate, wherein at least one refractory layer consisting of fine-grained, crystalline &ggr;-Al2O3 is deposited by reactive magnetron sputtering onto the moving substrate in a vacuum by pulsed magnetron sputtering in a mixture of a rare gas and a reactive gas at a pulse frequency set for 10 to 100 kHz. The deposition occurs with a rate of at least 1 nm/s with reference to a stationarily arranged substrate at a magnetron target power density in time average set for at least 10 W/cm2. The substrate temperature is in the range 400 to 700° C. and the flux of impinging particles onto each individual substrate is cyclically interrupted.
