Abstract
A method of compacting an anti-corrosive paint comprising metal particles and covering a mechanical part such as a turbine engine part, the method comprising a step of at least one spraying of solid ice particles on the part so as to densify and to make the paint electrically conductive.
Claims17
A method of compacting an anti-corrosive paint comprising metal particles and covering a mechanical part, the anticorrosive paint having a predetermined thickness, the method comprising:
- at least a first step of spraying solid ice particles on the part so as to densify and to make the paint electrically conductive, and without damaging removal portion of said anti-corrosive paint, wherein the first step of spraying is performed with predetermined parameters to avoid removal of a portion of said anti-corrosive paint;
- and
- at least a second step of spraying solid ice particles on the part with the same predetermined parameters,
- wherein the solid ice particles have dimensions of between 3 mm and 10 mm,
- wherein the first and second steps of spraying solid ice particles reduces the predetermined thickness between 5 to 10 μm.

A method, comprising the steps of:
- applying a paint comprising metal particles and covering a mechanical part, the metal particle comprises aluminium;
- polymerising the paint to form an anti-corrosive paint intended to protect the mechanical part;
- compacting the anti-corrosive paint by spraying solid ice particles having dimensions of about 3 mm on the anti-corrosive paint of said part so as to densify said anti-corrosive paint by reducing porosity in at least one layer of the anti-corrosive paint and making the paint electrically conductive, wherein the step of spraying solid ice particles reduces the predetermined thickness between 5 to 10 μm,
- wherein the metal particles located in the anti-corrosive paint after the step of compacting are in contact and increase the resistance of the anti-corrosive paint to corrosion, the anti-corrosive paint not being damaged by removal after compacting.
