Abstract
A mechanical part for an aircraft turbomachine is made of metal and includes at least one profiled surface configured to ensure an oil flow during operation. The surface has a hydrophobic and/or lipophobic coating or a surface texturing rendering the surface hydrophobic and/or lipophobic.
Claims14
A mechanical part for an aircraft turbomachine is made of metal and comprises at least one original non-roughened curved surface configured to ensure an oil flow during operation,
- wherein the part is an oil deflector or collector for a mechanical reduction gear, said original non-roughened curved surface is configured to be arranged facing a planet gear of the reduction gear,
- wherein said original non-roughened curved surface:
- either comprises a coating that is more hydrophobic and/or lipophobic than said original non-roughened curved surface,
- or comprises a surface texturing rendering said original non-roughened curved surface more hydrophobic and/or lipophobic, and
- wherein said coating covers said original non-roughened curved surface that is not roughened before coating, or said surface texturing is performed on said original non-roughened curved surface that is not roughened before texturing.

- either is coated with a coating that is more hydrophobic and/or lipophobic than said original non-roughened curved surface,
- or is textured and is non-coated after texturing so as to render said original non-roughened curved surface more hydrophobic and/or lipophobic than said original non-roughened curved surface,
- wherein said coating covers said original non-roughened curved surface that is not roughened before coating, or said surface texturing is performed on said original non-roughened curved surface that is not roughened before texturing.
