Abstract
A method for coating a part having a surface that has cooling fluid openings that adjoin cooling fluid ducts inside the part. A device analyzes the surface of a part having a surface that has cooling fluid openings which adjoin cooling fluid ducts inside the part, the device being usable in the aforementioned method. The disclosed device and/or the disclosed method is used during the manufacturing and/or overhauling of parts of a turbomachine.
Claims18
A process for coating a component comprising a surface comprising cooling fluid openings which adjoin cooling fluid channels in the interior of the component, the process comprising:
- a) introducing the component into an apparatus for a surface analysis of the component, where the apparatus comprises at least one measuring device and a fastening, where the fastening is suitable for being connected detachably either directly or indirectly to the component, where the apparatus is configured to carry out a two-part surface analysis, wherein in a first part of the two-part surface analysis the at least one measuring device is configured to determine a position of the cooling fluid openings on the surface of the component, and in a second part of the two-part surface analysis the at least one measuring device is configured to determine a three-dimensional shape of at least one cooling fluid opening,
- b) carrying out of the surface analysis of the component, where data in respect of the position of the cooling fluid openings on the surface of the component and in respect of the three-dimensional shape of at least one cooling fluid opening are detected,
- c) applying a coating to the component, where the cooling fluid openings are at least partly closed, and
- d) removing the coating in a region of the cooling fluid openings;
- wherein the at least one measuring device comprises:
- a first measuring device configured to determine the position of the cooling fluid openings on the surface of the component;
- and a second measuring device configured to determine the three-dimensional shape of at least one cooling fluid opening, and
- wherein the first measuring device and the second measuring device are different from each other.
A process for coating a component comprising a surface comprising cooling fluid openings which adjoin cooling fluid channels in the interior of the component, the process comprising:
- a) introducing the component into an apparatus for a two-part surface scan of the component, where the apparatus comprises at least one scanning device, where the apparatus is configured to carry out a two-part surface scan, wherein in a first part of the two-part surface scan the at least one measuring device is configured to determine a position of the cooling fluid openings on the surface of the component using a first measurement method, and in a second part of the two-part surface scan the at least one measuring device is configured to determine a three-dimensional shape of at least one cooling fluid opening using a second measurement method that is different than the first measurement method,
- b) carrying out of the two-part surface scan of the component, where data with respect to the position of the cooling fluid openings on the surface of the component and with respect to the three-dimensional shape of at least one cooling fluid opening are detected,
- c) applying a coating to the component, where the cooling fluid openings are at least partly closed, and
- d) removing the coating in a region of the cooling fluid openings.
