Method and apparatus for the treatment of a component

摘要

Apparatus, for the localised treatment of part of a blade (14), comprises an enclosure (16) that is placed in a spaced relationship around the blade (14). Nozzles (20) extend through the enclosure (16) and direct a flow of gas onto both sides of the blade (14). The gas may be heated or cooled prior to delivery to the nozzles (20). The gas jets impinge upon the blade (14) to treat it.
