  • Publication number: 20100145432
    Abstract: The present invention describes a method for producing an implant, in particular an intraluminal endoprosthesis, wherein the base material of the body (5) of the implant has biodegradable metallic material, preferably Mg or an Mg alloy. The method comprises the following steps: a. Provide the body (5) of the implant, b. Apply a first layer (10), which contains Ca ions and P ions, to at least a part of the surface of the body (5) and c. Apply a second layer (20), which is at least partially permeable for Ca ions and P ions, such that this at least largely covers the first layer (10). Furthermore, a corresponding implant is described, in which the degradation behavior can be controlled through the production according to the invention.

  • Publication number: 20100087915
    Abstract: The present invention relates to a method for manufacturing an implant, in particular an intraluminal endoprosthesis, with a body containing metallic material, preferably iron. To control the degradation of the implant, the method comprises the following steps: a) preparing the body of the implant, and b) incorporating hydrogen into at least a portion of the structure of the implant body near the surface. Furthermore, such an implant is described.

  • Publication number: 20100087914
    Abstract: The present invention proposes a method for manufacturing an implant, in particular an intraluminal endoprosthesis, having a body such that the body has metallic material. To control the degradation in a desired time window, e.g., between four weeks and six months, the following production method is performed: a) preparing the body of the implant, and b) plasma-chemical treatment of at least a portion of the surface of the body in an aqueous solution by applying a plasma-generating electric alternating voltage to the body (5) of the implant, said voltage having a frequency of at least approximately 1 kHz, to create a first layer. The invention also relates to an implant obtainable by such a method.

  • Publication number: 20090030506
    Abstract: A stent with a basic mesh comprising an at least largely biodegradable material and a coating (30) arranged on the biodegradable material. The basic mesh is covered completely by a coating, except for at least one degradation area (23, 25, 32), whereby the at least one degradation area (23, 25, 32) is designed as a recess in the coating (30).

  • Patent number: 5225069
    Abstract: A process for the production of white and black oxide ceramic surface films on silicon-containing light metal cast alloys by plasma-chemical anodic oxidation. An aluminum cast alloy is pickled with nitric acid and hydrofluoric acid and coated by plasma-chemical anodic oxidation in an aqueous electrolyte. Accordingly, a coating variant is provided particularly for construction parts of silicon-containing light metal cast alloys having complicated shapes which enables the production of uniformly thin oxide ceramic surface films in contrast to conventional coating variants.

  • Patent number: 5094727
    Abstract: By means of an electrolyte free of ammonia, cyanide, and fluoride, hence low in harmful substances and inoffensive to the environment, optically black coatings having a thickness of less than 10 microns and substantially equal optical absorption and thermal emission capability can be produced on light metals or alloys thereof by spark discharge anodizing. In comparison with prior art conversion coatings obtained by spark discharge anodizing, the coatings produced with this electrolyte have a substantially lower roughness of this electrolyte in spark discharge anodizing provides an alternative mode of coating particularly for structural components or subassemblies of complicated shapes having greater requirements for accuracy to gauge.

  • Patent number: 5035781
    Abstract: The invention relates to a cyanide-free electrolyte being harmless to the environment and to health which makes feasible the production of black surface layers on light metals or on alloys of the latter, preferably titanium, remaining deeply-black and adhesive even after extreme changes in the ambient temperature and having nearly equal values of the optical absorptivity of radiation and of the thermal emission capability (the .alpha./.epsilon.-ratio is about 0.95) by means of the anodic oxidation by spark discharge (ANOF-method). These layers are absolutely X-amorphous and show, hence, an ideal optically isotropic behavior regarding the reflection of radiation. Due to their minimum evolution of gases they offer a high thermovacuum stability. The electrolyte consists of an ammoniacal solution of K.sub.2 H.sub.2 PO.sub.4 potssium dihydrogenphosphate and K.sub.2 CRO.sub.4 potassium chromate. The homogeneity of the optically black layers is ensured by not using fluoride ions and employing acetate ions.
