Abstract: A method is provided for the nanostructuring and oxidation of a surface, which has an anodizable metal and/or an anodizable metal alloy, both being coated with an oxide layer, by way of a laser or particle radiation in an inert or reactive atmosphere and subsequent anodization. As a result, oxide nanostructures are formed on the entire surface, in titanium or titanium alloys in the form of nanotubes.

Abstract: A structural component for a vehicle has a surface with a riblet structure. The riblet structure includes a plurality of grooves, including a first groove having a first longitudinal section forming a first angle with a main longitudinal direction of the structural component. The first angle is larger than 0° and the main longitudinal direction corresponds to a flow direction of a fluid along the surface of the structural component.

Abstract: An endoprosthesis has a surface area which comprises a metal, a metal alloy, a ceramic, a platic material or a fiber-reinforced plastic material, and is uninterruptedly covered with a tissue-inductive or anticoagulant coating, at least partially. The surface area to which the coating is applied has been provided prior to that application with nanostructures having a height and a width in the range of 5 to 999 nm. A method for producing the endoprosthesis provides an endoprosthesis having these features.

Abstract: In a method for generating a surface having a solid polymeric material, which has surface structures with dimensions in the sub-micrometer range, the untreated surface, on which the structures are to be generated and which are accessible to laser radiation, is scanned once or multiple times using a pulsed laser beam in an inert gas atmosphere in such a way that adjacent light spots of the laser beam adjoin each other in a gapless manner or overlap and a certain range of a specified relation between process parameters is observed.

Abstract: In a method for producing a surface with a solid polymeric material which has surface structures having dimensions in the sub-micrometer range, the untreated surface on which the structures are to be produced and which is accessible to laser irradiation is scanned with a pulsed laser beam one or more times in a reactive gas atmosphere in such a manner that adjacent light spots of the laser beam have unbroken abutment or overlap with one another, and a certain range of a predetermined relation between method parameters is met, whereby the surface is chemically modified.

Abstract: A method for producing a metal or metal alloy surface or metal oxide layer or metal alloy oxide layer on the surface of a workpiece having surface structures with dimensions in the sub-micrometer range, involves scanning the entire surface of the metal or of the metal alloy or of the metal or metal alloy oxide layer on the metal or the metal alloy on which the structures are to be produced and which are accessible to laser radiation one or more times by a pulsed laser beam in such a way that adjacent flecks of light of the laser beam adjoin one another without gaps or overlap one another and a specific region of a predetermined relation between method parameters is satisfied.

Abstract: A method for producing a chemically modified metal surface or metal alloy surface or metal oxide layer or metal alloy oxide layer on the surface of a workpiece, which surface or layer includes surface structures having dimensions in the sub-micrometer range. The method involves scanning, one or several times using a pulsed laser beam, the entire surface of the metal or metal alloy, or the metal oxide layer or metal alloy oxide layer on the metal or metal alloy, on which surface or layer the structures are to be produced and which is accessible to laser radiation. The scanning is performed in an atmosphere containing a gas or gas mixture that reacts with the surface, such that adjacent flecks of light of the laser beam adjoin each other without an interspace in between or overlap and a predetermined range of a defined relation between process parameters is satisfied.
