System and method for local surface treatment

Abstract

The invention relates to a system for the local surface treatment of an aeronautical part ( 1 ) to be treated. Said system is characterised in that it comprises a plurality of containers ( 18, 19, 20, 21 ) each comprising a treatment product ( 22, 23, 24, 25 ), at least one bath enclosure ( 102 a, 102 b ) suitable for delimiting a fluid-tight space ( 26 a, 26 b ) between this bath enclosure ( 102 a, 102 b ) and a portion ( 101 a, 101 b ) of the part to be treated, and a controlled circuit ( 10 ) for supplying said fluid-tight space ( 26 a, 26 b ) with treatment product ( 22, 23, 24, 25 ) the containers ( 18, 19, 20, 21 ) connecting at least this container ( 18, 19, 20, 21 ) to said fluid-tight space ( 26 a, 26 b ) and comprising valves for managing the supply to the fluid-tight space by one or more containers from the plurality of containers.

1 . A system for the local surface treatment of an aeronautical part to be treated, the system comprising:
 a plurality of containers each comprising a treatment product;   at least one bath enclosure suitable for delimiting a fluid-tight space between the at least one bath enclosure and a portion of an aeronautical part to be treated; and   a controlled circuit supplying said fluid-tight space with said treatment product from at least one of the plurality of containers, and connecting the plurality of containers to said fluid-tight space said controlled circuit comprising valves managing a supply of said treatment product to the fluid-tight space by one or more ones of the plurality of containers.   
     
     
         2 . The local surface treatment system according to  claim 1 , wherein the at least one bath enclosure comprises a wall having an opening, adapted to cover the portion of the aeronautical part to be treated so that the fluid-tight space is delimited by the wall of the at least one bath enclosure and the portion of the aeronautical part to be treated. 
     
     
         3 . The local surface treatment system according to  claim 2 , wherein the opening is surrounded by seals. 
     
     
         4 . The local surface treatment system according to  claim 1 , wherein the at least one bath enclosure comprises a device controlling a temperature in the fluid-tight space, said device comprising a heater and a temperature measurer. 
     
     
         5 . The local surface treatment system according to  claim 1 , wherein the at least one bath enclosure comprises a stirrer stirring the treatment product in the fluid-tight space. 
     
     
         6 . The local surface treatment system according to  claim 1 , wherein the aeronautical part to be treated is a large-sized part. 
     
     
         7 . The local surface treatment system according to  claim 1 , wherein the at least one batch enclosure comprises a multiplicity plurality bath enclosures adapted to delimit a plurality of fluid-tight spaces between each of the multiplicity of bath enclosures and a plurality of portions of the aeronautical part to be treated. 
     
     
         8 . The local surface treatment system according to  claim 1 , further comprising an electricity generator comprising a negative pole connected to the at least one bath enclosure and a positive pole connected to the aeronautical part to be treated. 
     
     
         9 . The local surface treatment system according to  claim 1 , further comprising a filtration device arranged on the controlled supply circuit. 
     
     
         10 . A method for the local surface treatment of an aeronautical part to be treated, in which at least one treatment product is applied to a portion of the aeronautical part to be treated, the method comprising:
 prior to the application of the at least one treatment product to the portion of the aeronautical part to be treated,   fitting a bath enclosure on the aeronautical part to be treated, so as to delimit a fluid-tight space between the bath enclosure and the portion of the aeronautical part to be treated; and,   supplying the fluid-tight space from one or more containers with the at least one treatment product.
