Definitions

  • the invention relates to systems and methods for local surface treatment of industrial parts.
  • the invention relates to systems and methods for the local treatment of metal parts intended for aeronautical use.
  • the treatment of the surfaces of parts consists in applying one or more treatment products to the surface of a part to form a coating, the purpose of which is to improve the protection of the part, for example against corrosion, better chemical or mechanical resistance, etc., or a change in the external appearance of the part, for example by applying a layer of paint.
  • the coating is formed by applying the treatment products to the part by soaking said piece in one or more baths each comprising a treatment product.
  • the baths are located in tanks adapted to the size of the room to be treated. This soaking process is already proven in the field of aeronautics and allows the obtaining of qualified coatings in accordance with the constraints of this field, in particular in terms of performance and environmental constraints.
  • devices allow the local application of a treatment product by the use of pads soaked with this treatment product. Nevertheless, these devices are used by manual application on the part of the part to be treated. Thus the application times are long and not compatible with a series production line. Moreover, the manual application is not very reproducible, and can generate coulures likely to pollute and degrade peripheral areas to those treated. Finally, these applications have not been systematically certified in the aeronautical field, and therefore can not be used to form certain types of coatings.
