摘要： A method of manufacturing a hollow machine blade consisting of two skins ining an internal cavity and interconnected by stiffeners comprises: forging and machining the primary components of the blade, including forming a reserve of material in localized regions of the inner faces of the skins, trunnion forming elements at the ends of the components, and locating holes in the components; deposition of diffusion barriers involving application of a mask, cutting the mask to a predetermined pattern using a special-purpose tool, peeling away portions of the mask, deposition of a coating product, peeling away the remainder of the mask, prefiring treatment, cleaning and checking; assembly of the primary components followed by isostatic-pressure diffusion welding; and subjecting the assembly to inflation under gas pressure and superplastic forming in a mould in order to shape the skins and form the interconnecting stiffeners, including the steps of cold-debonding the primary components, causing flow of the material reserved in the overthickness around the blade cavity, and extraction of the blade from the mould by way of mechanical means placing the blade under constraint after the forming of the blade.
