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.

The process includes maintaining a low pressure glow discharge between the substrate to be pre-treated and a counter-electrode, where the counter-electrode composed of at least a component of the coating to be deposited in the vacuum coating process. The process also includes periodically alternating a polarity of the substrate to act as a cathode or as an anode of the low pressure glow discharge, and individually controlling at least one of pulse length and discharge voltage in both polarities. A frequency of alternation of the polarity is set within a range of between 1 Hz and 1000 kHz. The apparatus includes an evacuatable vacuum chamber, a substrate holder positioned to hold a substrate to be pre-treated, at least one counter-electrode, and an alternating voltage generator coupled to the substrate to be pre-treated and the at least one counter-electrode. The substrate and the counter-electrode are mounted in a potential-free manner.

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.
