Abstract

A method for coating a turbine engine component comprises the steps of: providing a turbine engine component having at least one sacrificial attachment on a first side; grasping the turbine engine component via the at least one sacrificial attachment to position a first surface of the turbine engine component relative to a source of coating material; and applying a coating to said first side.

First claim

What is claimed is:

1. A method for coating a turbine engine component comprising the steps of:
providing a turbine engine component having opposed sides and having at least one sacrificial attachment projecting from a rear surface located between said opposed sides and having a plurality of non-sacrificial studs projecting out of the rear surface;
casting said turbine engine component with said at least one sacrificial attachment so that said at least one sacrificial attachment is located in a location where the turbine engine component is reinforced;
grasping said turbine engine component via said at least one sacrificial attachments to position a first surface opposite said rear surface of said turbine engine component relative to a source of coating material;
applying a coating to said first surface;
rotating said turbine engine component by 180 degrees while grasping said turbine engine component via said at least one sacrificial attachment; and
applying a coating to said rear surface of said turbine engine component opposed to said first surface.

2. The method of claim 1 , further comprising:
removing said at least on sacrificial attachment.

3. The method of claim 2 , wherein said removing step comprises machining said at least one sacrificial attachment.

4. The method of claim 1 , wherein said at least one sacrificial attachment has a threaded end and said grasping step comprises engaging said threaded end.

5. The method of claim 1 , wherein said providing step comprises welding said at least one sacrificial attachment to said turbine engine component.

6. A system for coating a turbine engine component comprising:
said turbine engine component having opposed sides and a rear surface between said opposed sides, a plurality of non-sacrificial studs projecting out of the rear surface, at least one sacrificial attachment projecting from said rear surface, wherein said at least one sacrificial attachment comprises a stud integrally formed with said turbine engine component;
a source of coating material;
means for grasping said turbine engine component via said at least one sacrificial attachment to position a first surface of said turbine engine component relative to said source of coating material so that said first surface may be coated, said first surface located opposite said rear surface; and
means for rotating said turbine engine component while said at least one attachment is being grasped so that said rear surface of said turbine engine component may be coated.

7. The system of claim 6 , wherein said turbine engine component is a combustor panel.

8. The system of claim 6 , further comprising a stress concentrator located at a base of said stud.

9. The system of claim 6 , further comprising said stud having a threaded end.

10. The system of claim 9 , wherein said grasping means comprises a holder having an opening through which said stud passes and a nut and washer arrangement for engaging said threaded end.

11. The system of claim 6 , wherein said at least one attachment is welded to said turbine engine component.

12. The system of claim 6 , wherein said at least one sacrificial attachment comprises a rod projecting from said rear surface of said turbine engine component.
