    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: A composite coating (1) resistant to wear is applied onto a substrate (2) and contains a mixture of hard material particles (3) and particles (5) of a solid lubricant (6). The particles (3, 5) are incorporated in a binder alloy (4). The lubricant particles are each enclosed by a protective envelope (7). The protective envelope substantially prevents bonding between components of the lubricant (6) on the one hand and components of the binder alloy (4) as well as of the hard material particles (3) on the other hand.
