METHOD FOR TREATING TURBINE BLADES AND DEVICE THEREFOR

摘要

The method involves applying a protective layer, and reopening cooling air holes (2) partially or totally closed by the protective layer. Coordinates over a location of the cooling air holes are detected before applying the protective layer by a laser triangulation sensor (4) based on an optical triangulation process with a light source generating a light beam and a light detector. Data is used after application of the protective layer for controlling a removing device to remove the protective layer partially or completely covering the cooling air holes. An independent claim is also included for a device for determining position of cooling air holes in turbine blades.
