  • Patent number: 8986792
    Abstract: To apply a thermal barrier coating (10), a plasma jet (5) is generated by a plasma torch in a work chamber (2) and is directed to the surface of a substrate (3) introduced into the work chamber, and a ceramic coating material is applied to the substrate surface by means of PS-PVD, wherein the coating material is injected into the plasma jet as a powder and is partly or completely vaporized there. On applying the thermal barrier coating, in a first workstep the feed rate of the injected powder is set so that a large part of the injected powder vaporizes, wherein the coating material condenses from the vapor phase on the substrate surface and forms mixed phases with the material of the substrate surface.

  • Publication number: 20120308733
    Abstract: To manufacture a thermal barrier coating structure on a substrate surface, a working chamber having a plasma torch is provided, a plasma jet is generated in that a plasma gas is conducted through the plasma torch and is heated therein by means of electric gas discharge, electromagnetic induction or microwaves, and the plasma jet is directed to the surface of a substrate introduced into the working chamber. To manufacture the thermal barrier coating, a voltage is additionally applied between the plasma torch and the substrate to generate an arc between the plasma torch and the substrate and the substrate surface is cleaned by means of the light arc, wherein the substrate remains in the working chamber after the arc cleaning and an oxide layer is generated on the cleaned substrate surface and a thermal barrier coating is applied by means of a plasma spray process.

  • Publication number: 20120231211
    Abstract: In the presented method for the manufacture of a thermal barrier coating structure (2) on a substrate surface (3) a ceramic coating material is applied onto the substrate surface by means of plasma spraying, wherein the thermal barrier coating structure includes at least two differently produced thermal barrier coatings (2.1, 2.2). For the manufacture of the one thermal barrier coating (2.1), the coating material is sprayed onto the substrate surface in the form of a powder jet by plasma spraying at atmospheric pressure (atmospheric plasma spraying or in abbreviation APS), and for the manufacture of the other thermal barrier coating (2.2) the coating material is applied onto the substrate surface by means of plasma spraying-physical vapor deposition or in abbreviation PS-PVD, such that a layer having elongate corpuscles develops on the substrate surface, which corpuscles form an anisotropic microstructure and are aligned essentially perpendicular to the substrate surface.

  • Publication number: 20120087802
    Abstract: A method is proposed of coating a surface of a body which has at least one throughgoing bore having an inlet and having an outlet, wherein the outlet is provided in the surface to be coated, in which method the coating takes place by means of thermal spraying, wherein, during the thermal spraying, the bore is flowed through by a fluid which flows out through the outlet of the bore and substantially prevents a constriction of the bore caused by the coating.

  • Publication number: 20090136781
    Abstract: A method for the generation of a functional layer is proposed in which a coating material is sprayed onto a surface of a substrate in the form of a jet of powder by means of a plasma spraying process, wherein the coating material is injected at a low process pressure which is less than 10 000 Pa into a plasma, which defocuses the jet of powder and is melted partly or completely there, wherein a plasma with adequately high specific enthalpy is produced, so that a substantial proportion, amounting to at least 5% by weight of the coating material passes over into the vapour phase and an anisotropically structured layer arises on the substrate, wherein elongate corpuscles, which form an anisotropic microstructure, are aligned standing largely perpendicular to the surface of the substrate and transition regions with little material delimit the corpuscles with respect to one another.

  • Publication number: 20060021728
    Abstract: A method is disclosed for producing a reinforced component from a composite material (MMC). A metallic matrix material is reinforced by embedded fibers or particles, for which purpose a semi-finished product is prepared that comprises fibers and particles or both, together with a metallic matrix material. Forming is effected by thixoforming in a mold at a temperature above the solidus temperature and below the liquidus temperature of the metallic matrix material. The method allows to manufacture near-net-shaped products with excellent mechanical properties.
