Method for producing a surface structure, in particular on a surgical implant
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...

| description | 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 |
