Abstract
A method for coating a shroud assembly is provided that includes inserting the shroud segment into a clamping fixture such that at least two edges of the shroud are masked by the clamping fixture, mounting the clamping fixture into a spraying fixture such that the shroud segment is oriented in approximately the same orientation as a sprayer, and moving the sprayer and the spraying fixture relative to each other at predetermined rates apply a layer of coating to the shroud segment.
Claims14
An apparatus for clamping and locating shroud segments during a spraying operation, said apparatus comprising:
- a base;
- a pair of elongated arms, each comprising a first end and an opposite second end, each of said first ends coupled to said base;
- a clamping element coupled to each said arm second end, said clamping element for securing a shroud segment to said base, such that at least one edge of the shroud segment is positioned against and masked by said clamping element;
- and
- a locating member comprising a yoke defining a slotted opening sized to receive a locating rib extending from the shroud segment, said locating member is coupled to said base between said pair of arms for positioning the shroud segment with respect to said base, said locating member configured to engage a shroud segment surface for positioning the shroud segment.
An apparatus for clamping gas turbine engine shroud segments, said apparatus comprising:
- a base;
- a pair of arms comprising opposite first and second ends, each of said first ends coupled to said base;
- a clamping element coupled to each said arm second end, said clamping element configured to clamp the shroud segments to said base such that at least one edge of each shroud segment is positioned against and masked by said clamping element;
- and
- a locating member comprising a yoke comprising a slotted opening defined therein, said opening sized to receive at least a portion of the shroud segment therein.
