Abstract: The invention relates to a grain-oriented magnetic steel sheet including an electrically insulating coating made of an amorphous carbon-hydrogen network, which is applied after final annealing in order to ensure electrical insulation of the individual layers of the sheet. The grain-oriented magnetic steel sheet including the electrically insulating coating made of an amorphous carbon-hydrogen network can be used in transformers.

Abstract: A substrate includes a metal diamond-like-carbon coating composed of a first layer and second layer deposited thereupon and having a thickness of about 0.5 micrometer to 10 micrometers. The first layer is composed of a transition metal and includes a first surface and a second surface in contact with the substrate. The second layer is composed of carbon and a transition metal selected from the group consisting of tungsten, niobium, titanium and combinations thereof, and also includes a first surface and a second surface in contact with the first surface of the first layer. The metal-containing diamond-like-carbon coating compositions possesses an abrasive wear rate of no more than about 10×10?15 m3m?1N?1 over a negative biasing potential range of about ?50 volts to ?750 volts.

Abstract: The invention relates to grain-oriented magnetic steel sheet comprising an electrically insulating coating, made of an amorphous carbon-hydrogen network, which is applied after final annealing in order to ensure electrical insulation of the individual layers of sheet, said grain-oriented magnetic steel sheet being used e.g. in transformers. The invention also relates to a method for producing the grain-oriented magnetic steel sheet comprising an electrically insulating coating made of an amorphous carbon-hydrogen network, which method consists of coating of the strip-shaped sheet substrate taking place in a continuous strip method. The application is to be published without a Figure.

Abstract: Process for producing wear-resistant layers of cubic boron nitride or wear-resistant layers containing cubic boron nitride by sputtering with RF or DC voltage in the operating mode of an unbalanced magnetron, in which the plasma is generated by DC arc discharges or DC operated magnetron cathodes. The initial target for the production of the layer from which the material is removed comprises electrically conductive material containing boron, preferably boron carbide, and, in the process, the reactive process is conducted with the addition of N.sub.2 and Ar in such a way that the necessary stoichiometric ratio BiN in the layer can be adjusted.

Abstract: Hard coatings for mechanically and corrosively stressed elements are applicable to arbitrarily chosen substrate materials. The mentioned elements can be tools, cutting inserts or bearings. Further, applications are possible in electronics and optics and also for decorative purposes. Hard coatings on the basis of carbon and boron nitride, produced by known techniques, are obtained which can be used in a wide field of application, exhibiting, besides a high hardness, maximum adhesion and good protection against wear and corrosion at high temperatures. The C and B/N coatings consist of amorphous network structures with short range orders similar to that of the hexagonal crystalline phases of carbon and boron nitride, have hydrogen concentrations between 5 atom-% and 50 atom-% and additional components consisting of metals and/or boron and or silicon and/or noble gases in the concentration range between 1 atom-% and 85 atom-%.
