Masking Systems
A masking system for selectively masking a component includes a first shell half and a second shell half. The second shell half is configured to be secured to the first shell half such that at least a portion of the first shell half overlaps the second shell half when the component is retained by the masking system. A protrusion extends from one of the first shell half and the second shell half. The protrusion is configured to cover an edge of the component.
1 . A masking system for selectively masking a component, the masking system comprising:
a first shell half;
a second shell half configured to be secured to the first shell half such that at least a portion of the first shell half overlaps the second shell half when the component is retained by the masking system; and
a protrusion extending from one of the first shell half and the second shell half, the protrusion configured to cover an edge of the component.
2 . The masking system of claim 1 , wherein the protrusion is configured to be removable.
3 . The masking system of claim 1 configured to retain the component for a coating process.
4 . The masking system of claim 3 , wherein a distribution of coating on the component is defined via a profile of the protrusion.
5 . The masking system of claim 3 , wherein the first shell half has a first tab, and the second shell half has a second tab that corresponds to the first tab when the first shell half is brought into contact with the second shell half.
6 . The masking system of claim 5 , including a fastener extending through each of the first tab and the second tab.
7 . The masking system of claim 5 , including interlocking clips extending through each of the first tab and the second tab.
8 . The masking system of claim 1 , wherein the masking system is additively manufactured.
9 . The masking system of claim 8 , wherein the component is a component of a gas turbine.
10 . The masking system of claim 9 , wherein:
the component is a gas turbine blade; and
the edge is a trailing edge of the gas turbine blade.
11 . The masking system of claim 10 , wherein the masking system is configured to mask at least a dovetail of the gas turbine blade.
12 . The masking system of claim 1 , wherein the first shell half includes a first shelf, and the second shell half includes a second shelf, each of the first shelf and the second shelf configured to contact the component.
13 . The masking system of claim 1 , wherein the masking system further includes a mounting portion for mounting the masking system to a surface.
14 . The masking system of claim 13 , wherein the mounting portion is removably coupled to one of the first shell half and the second shell half.
15 . An additively manufactured masking system for selectively masking a blade of a gas turbine for a coating process, the masking system comprising:
a first shell half having a wall corresponding to a suction side of the blade;
a second shell half having a wall corresponding to a pressure side of the blade; and
a protrusion extending from one of the first shell half and the second shell half;
wherein, a distribution of coating on the blade during the coating process is defined via a profile of the protrusion.
16 . The additively manufactured masking system of claim 15 , wherein the protrusion is removable.
17 . The additively manufactured masking system of claim 15 , wherein the protrusion has a generally spherical shape.
18 . The additively manufactured masking system of claim 15 , wherein the protrusion has a generally trapezoidal shape.
19 . A masking system for selectively masking a component, the masking system comprising:
a first shell having a first cover and a first tab, the first cover having at least a first recess and a first peak, each of the first recess and the first peak corresponding to the component at a first side thereof; and
a second shell having a second cover and a second tab, the second cover having at least a second recess and a second peak, each of the second recess and the second peak corresponding to the component at a second side thereof, the second side opposing the first side.
20 . The masking system of claim 19 , wherein the component is a gas turbine vane.
