<p>There is disclosed apparatus (10) for use in the thermal processing of a component (1) such as an aero-engine turbine or compressor blade. The apparatus (10) comprises holding means (13) for retaining a first part of the component (1) in a fixed position and forming means (21) spaced from the holding means (13) and adapted to hold a second part of the component (1) in a desired position and/or orientation relative to the first part. In use, a component (1) is mounted within the apparatus (10) such that a first part of the component (1) is retained by the holding means (13) in a fixed position. The forming means (21) is then applied to a second part of the component (1) such that it is held in a desired position and/or orientation relative to the first part. The component (1), whilst held in the apparatus (10) is then subjected to thermal treatment, eg by being placed in a preheated oven, typically at 500-700 °C for a period of several hours.</p> |
