    摘要: The present invention describes a coated cutting tool for metal machining. The coating is formed by one or more layers of a refractory compound of which at least one layer of fine-grained, crystalline &ggr;-phase alumina, Al2O3, with a grain size of 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;-angles 45.8 and 66.8 degrees when using Cu&kgr;&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: A process an device for ion-supported vacuum coating. The process and the affiliated device is intended to permit the high-rate ating of large-surfaced, electrically conductive and electrically insulating substrates with electrically insulating and electrically conductive coatings with relatively low expenditure. The substrates are predominantly band-shaped, in particular plastic sheets with widths of over a meter. According to the invention, in an intrinsically known device for vacuum coating, alternating negative and positive voltage pulses are applied to the electrically conductive substrate or in electrically insulating substrates, to an electrode disposed directly behind them, e.g. the cooling roller, relative to the plasma or to an electrode that is disposed almost at plasma potential. The form, the voltage, and the duration of the pulses are adapted to the coating task and the material. The process is used particularly for depositing abrasion protection, corrosion protection, and barrier coatings. The user is the packaging industry, among others.

    摘要: Magnetron discharges are pulse-operated to avoid the so-called “arcing”. In the case of magnetron discharges from alternating current-fed magnetrons, the process is limited to the minor power of the energy supply because of the load-carrying capacity of the required electric components. When the magnetron discharges are fed by direct current, their effectiveness deteriorates because of the deposition of layers on the anode surfaces. The new process should enable a high supply power and prevent arcing. In magnetron discharges with at least two magnetron electrodes, the energy is supplied in such a way that at least one magnetron electrode is a cathode or anode and a number n1 of direct current pulses of said polarity is supplied. The poles of at least one magnetron electrode are then reversed and a number n2 of direct currents of this polarity are supplied. The process is carried on in this manner, the frequency of the direct current pulses being higher than that of the polarity reversals. The energy supply effectiveness is thus improved. This process and system enable the production of layers having the most different properties, for example for the glass, packaging, electronic, and machine construction industries.
