Abstract
A method of masking a surface of a gas turbine engine component wherein the ability of a masking member to retain the shape of the surface to which it is applied is used as a primary fixing strategy to releasably hold the masking member in position over the surface of the gas turbine engine component.
Claims11
A method of masking a surface of a gas turbine engine component, the method comprising the steps of:
- providing a masking member having the ability to retain the shape of the surface to which the masking member is applied;
- and
- using said ability as a primary attachment to releasably fix the masking member in position over the surface of the gas turbine engine component.
A method of temporarily protecting a surface of a gas turbine engine component while the same is being processed, the method comprising the steps of:
- fixing an adhesive-free foil in position on a surface of the gas turbine engine component by directly laying the foil against the surface in conformity to a shape of said surface, the frictional contact between the adhesive-free foil and the surface maintaining the adhesive-free foil in position on the gas turbine component, processing the gas turbine engine component, and removing the adhesive-free foil from said surface.
A method of holding a component during processing thereof, the method comprising the steps of:
- providing a foil having the ability to retain the shape of the component to which the foil is applied;
- and
- fixing the foil in position over a portion of the component by plastically deforming the foil in close fitting relation with the component, and
- encapsulating the portion of the component covered by the foil in a body of hardenable material.
