Claim 0:
1. A process for coating an aircraft turbomachine component with an erosion-resistant coating, the process comprising:
heating the aircraft turbomachine component to a temperature, then
once the aircraft turbomachine component has been heated to said temperature, initiating deposition of the erosion-resistant coating and depositing the erosion-resistant coating while the heating of said aircraft turbomachine component is maintained, the erosion-resistant coating being deposited by hot powder-coating of a powder including a mixture of a monomer of the polymer that forms said erosion-resistant coating and a cross-linking agent on said heated aircraft turbomachine component made of an organic-matrix composite material or of a metallic material, said polymer being a polyurethane or silicone polymer, said polymer having a glass transition temperature of less than or equal to −30° C., and wherein the monomer is crosslinked on contact with the heated aircraft turbomachine component.
