Abstract
Official abstract text for this publication.
A method for assembling two blades of a turbomachine nozzle, includes positioning a first surface of a first blade and a second surface of a second blade facing one another, the first and second surfaces being spaced apart from one another by an assembly clearance, and vapor phase aluminizing the first and second surfaces so as to fill the assembly clearance.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for assembling two blades of a turbomachine nozzle, comprising: positioning a first surface of a first blade and a second surface of a second blade facing one another, said first and second surfaces being spaced apart from one another by an assembly clearance; implanting solder beads in the first and second surfaces so as to maintain a positioning between the positioning step and the aluminising step, and vapour phase aluminising the first and second surfaces so as to fill the assembly clearance. 2. The method for assembling according to claim 1 , further comprising a diffusion step, following the aluminising step. 3. The method for assembling according to claim 1 , further comprising depositing a layer favouring aluminising, preceding the positioning. 4. The method for assembling according to claim 3 , wherein the layer is obtained by electrolytic route. 5. The method for assembling according to claim 3 , wherein the layer is obtained by physical vapour deposition. 6. The method for assembling according to claim 1 , further comprising performing a surface treatment of the first and second surfaces, preceding the positioning step. 7. The method for assembling according to claim 6 , wherein the surface treatment comprises degreasing the first and second surfaces with acetone under ultrasonic agitation. 8. The method for assembling according to claim 1 , further comprising masking at least one zone of the first blade, preceding the positioning step. 9. The method for assembling according to claim 1 , further comprising determining the assembly clearance, preceding the positioning step.
