    摘要: An arrangement for holding and cooling bearing shell blanks (2) positioned one next to the other during a coating process in a vacuum chamber, has cooling body and work piece holding pairs (3) which are detachable from each other and which are connected to one another via a cooling surface (9) and a heat transmission surface (7). A work piece holding part (5) of the cooling body and the work piece holding pair (3) is implemented so that the bearing shell blanks (2) are placed in a concave bearing surface (32) of the holding part during the coating process and are kept, over their entire surface, at a temperature determined by the cooling surface temperature. A temperature gradient can be formed if teflon foil strips are placed on the bearing surface. These allow only a direct heat contact of the apex of the bearing shell blanks (2) with the bearing surface. At the apex then, a deposition of fine particles with a high surface hardness, and at the margins a deposition of coarse particles with a correspondingly lesser surface hardness, take place. During the coating, the work piece holding parts (5) can already be loaded whereby the pass in the production of bearing shells (2) can be considerably shortened.

    摘要: For some applications of slide layers, for example in connecting rod bearings of internal combustion engines, for individual sites of a formed piece, high load bearing capability are required while for other places of the same formed piece good embedding abilities are demanded. A composite material with a slide layer applied by cathode sputtering of a tightly cohesive matrix and an insoluble component distributed statistically in it, is adapted to these opposite demands in that the diameter of the particle of the insolutble material has gradients at predetermined sites, which extend parallel to the surface of the slide layer, and to which slide layer hardness gradients correspond. These gradients are generated during the cathode sputtering process in the substrate to be coated to form a growing slide layer having temperature gradients which are maintained and which extend parallel to the substrate surface.

    摘要: In order to obtain coatings of greater density and compactness than were possible until now when coating substrates with magnetic field-supported cathode sputtering, a given fraction of metal vapor obtained by vaporization of an electric arc discharge from the anode or cathode is deposited on the functional areas of the substrates together with the sputtered material and, specifically, at least 5 atom percent of the total metal fraction of the coating to be deposited averaged over time is applied by vaporization of an electric arc discharge. A suitable vacuum coating installation for carrying out the method has within a vacuum chamber, a device for vaporizing a part of the coating-forming material with an electric arc discharge and an additional device for magnetic field-supported sputtering of another part of the coating-forming material.

    摘要: Machine elements formed which overcome the problems associated with rolling bearings or rolling drive units, which, apart from load under rolling are simultaneously exposed to frictional load, which leads in particular zones to frictional wear. In order to keep this to a minimum the invention teaches to apply on the effected surfaces of such structural parts a coating of a friction bearing material, which, however, according to the findings of the invention must be applied with the PVD method and must have a thickness of the order of magnitude of the surface roughness of the base body; known thicker friction bearing coatings are not suitable. The invention is especially for forming gear wheels, rolling bearings, shafts, compressor screws, and rolling pistons.

    摘要: In the previously used methods for the deposition of layers on surfaces by means of chemical reactions with gases, which are introduced into the reaction room or chamber (chemical vapor deposition, CVD), electrical glow discharge and mainly high-frequency discharges were used for the activation of the reactants. According to the invention, the maintaining of a low-voltage arc discharge in the reaction room during the coating is recommended. The surprising result of this is a considerably stronger activation and ionization and a more uniform coating also on surfaces of complex shape.
