摘要：
A method for coating a nozzle segment, the method comprising separating an outer shroud and an inner platform of the nozzle segment along pathways that bisect a first stator vane and a second stator vane of the of the nozzle segment, coating the first stator vane and the second stator vane after separating the outer shroud and the inner platform, and rejoining the separated outer shroud and the separated inner platform after coating the first stator vane and the second stator vane.
