Abstract
Official abstract text for this publication.
A mask assembly for a gas turbine engine component includes a second mask that at least partially overlaps a first mask to fit a platform of a gas turbine engine component.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of masking a component of a gas turbine engine comprising: slidably abutting a first mask and a second mask to at least partially overlap and fit a gas turbine engine component; and fitting a first skirt of the first mask and a second skirt of the second mask to fit a platform of the gas turbine engine component, wherein the first skirt and the second skirt partially overlap one another and are each L-shaped in a cross-section, the partial overlapping of the first and second skirts forming a mated mask around the gas turbine engine component, the mated mask exhibiting a T-shaped cross-section that is perpendicular to each of the L-shaped cross-sections of the first and second skirts. 2. The method as recited in claim 1 , further comprising: fitting a post that extends from the first mask into a slot in the second mask. 3. The method as recited in claim 1 , further comprising: clipping the first mask to the second mask. 4. The method as recited in claim 3 , further comprising: spraying a coating onto the gas turbine engine component; and unclipping the first mask from the second mask to remove the first mask from the second mask without chipping the coating. 5. The method as recited in claim 1 , further comprising: fastening the first mask to the second mask. 6. The method as recited in claim 5 , wherein a fastener is mounted around a first handle of the first mask and a second handle of the second mask when fastening the first mask to the second mask.
