Method for coating metal surfaces of substrates, and objects coated according to said method
A coating, a method for coating surfaces, and the coated surfaces. The method includes providing a substrate with a cleaned metal surface; contacting and coating the metal surface with an aqueous composition having a ph of from 0.5 to 7.0 and in the form of a dispersion and/or a suspension; optionally rinsing the organic coating; and drying and/or baking the organic coating, or optionally drying the organic coating and coating same with a similar or another coating composition thereto. The composition contains a complex fluoride in a quantity of 1.1 10.sup.−6 mol/l to 0.30 mol/l based on the cations. An anionic polyelectrolyte in a quantity of 0.01 to 5.0 wt % based on the total mass of the resulting mixture is added to an anionically stabilized dispersion made of film-forming polymers and/or a suspension made of film-forming inorganic particles.

Coating of a vascular endoprosthesis
The invention relates to a method for coating a vascular endoprosthesis, wherein the outside of the vascular endoprosthesis is wetted at least partially with a first solution of an active substance, the vascular endoprosthesis is moved in a rotational movement about the longitudinal axis of the vascular endoprosthesis, and a radially acting mechanical force is applied to the outside of the vascular endoprosthesis. The rotational movement has the effect that the solution is carried outward by the centrifugal force, such that no active substance deposits in the interior of the vascular endoprosthesis. The application of a mechanical force to the outside of the vascular endoprosthesis then has the effect of creating crystallization nuclei, such that the active substance can crystallize out.
