    摘要: In the method for producing a surface structure, material is ablated by means of a liquid jet (1). The jet (1) is emitted from a nozzle (10) under high pressure (p). In this an ablation location (3) is controlledly moved on a surface (20a) of a substrate (20) to be structured with the production of a predetermined macro-topography (2′) or a largely planar surface, namely through moving the nozzle and/or the substrate. The substrate is in particular part of a surgical implant. The liquid of the high pressure jet (1) is emitted at a predetermined diameter d of the nozzle with a sufficiently high pressure p so that through the material ablation a linear track (2) with quasi-fractal micro-topography (4) is produced. In this the track width D is at least twice as large as d. Values for p and d are provided in the following range: 100 bar 3000 bar and d>0.03 mm.

    摘要: The electrolysis occurs as a high-pressure electrolyzer, oxygen being produced on one side and hydrogen on the other side, with corresponding pressure. The gases may optionally be stored without additional compression. The PEM fuel cell process is used in reverse for the process. It is advantageous that excess energy may be used by wind power plants. In the associated device, a high-pressure electrolyzer (1) is present which is operated using environmentally friendly air power. Due to the improved operating point of the high-pressure electrolyzer, improved economy results for the generation process compared to the prior art, in particular for hydrogen as an energy storage.

    摘要: The object comprises a glass-metal film (1) with a metal matrix (2) which has solidified in an at least partly glass-like form and which may comprise hard particles (3, 3a) in the form of primary precipitates from the molten mass. The glass-metal film (1) is provided on at least one side (4) with a top layer (5) comprising a hard material which is harder than the glass-metal film (1). The top layer (5) may be formed by a base layer (7) with embedded hard material particles (8), e.g. of diamond or cubic boron nitride, or by a homogeneous hard material, e.g. diamond-like carbon. The result is a surface quality which can be separately influenced by the composition of the alloy of the glass-metal film (1). The object may be formed either as a parting tool or as a structural part with special wear and/or sliding properties.
