  • Publication number: 20110045309
    Abstract: The invention relates to a method for adjusting the friction coefficient of the surface of a metallic workpiece by applying and hardening a single-layer or multi-layer coating having a boundary surface facing toward the workpiece and having a boundary surface facing away from the workpiece, wherein one or more base coats each having at least one binding agent and metallic particles, is/are applied in layers, and at least one of the base coats has at least one lubricant.

  • Publication number: 20110000793
    Abstract: The invention relates to a coating method for a workpiece, including the following method steps: a) applying a coating liquid to the workpiece, wherein the coating liquid comprises an ionic liquid containing ions of at least one element, b) electrochemically depositing a layer of the at least one element from the coating liquid on the workpiece, c) removing the workpiece from the coating liquid, d) removing excess coating liquid from the workpiece. In order to suggest an industrially suitable coating process, particularly for workpieces having at least a partial metal surface, using stable, durable baths, it is provided that the temperature of the workpiece is set such that the temperature of the coating liquid deviates by no more than 10° C.

  • Publication number: 20090289212
    Abstract: A process for producing porous films (2), with the film (2) having a polymer matrix (M) and discrete domains (D) being provided in the matrix (M). According to the invention, it is proposed that the film (2) be subjected to a field for selective excitation of the domains (D), that the domains (D) be heated selectively relative to the remainer of the matrix by the excitation and that the pores (12) be produced in the domains (D) or in the region of the domains (D).

  • Publication number: 20090291279
    Abstract: A flat bonding structure (1), such as adhesive tape, adhesive film or adhesive edge, especially for use in construction, with at least one bonding region (2) which has at least one adhesive. In order to create a bonding structure (1) which has good temperature stability, good long-term adhesive power, and high initial adherence, the bonding region (2) has at least one first component region (4) with a first adhesive (5) and at least one second component region (6) with a second adhesive (7) and that the first adhesive (5) and the second adhesive (7) have different adhesive properties.
