| abstract |
The invention relates to a polyelectrolyte-based nanostructured anticorrosion coating, comprising at least one main compartment which comprises:n a polyelectrolyte multilayer ( 1 ) doped with at least one anticorrosion agent ( 4 ), and an upper multilayer ( 2 a ) acting as a barrier to the diffusion of the dopants, and whose upper surface corresponds to the upper surface of the main compartment,n nand optionally one or more secondary compartments, each comprising:n a polyelectrolyte multilayer ( 8; 11 ) doped with at least one functional agent other than an anticorrosion agent, and an upper multilayer ( 2 b; 2 c ) acting as a barrier to the diffusion of the dopants, and whose upper surface corresponds to the upper surface of the secondary compartment. nn The invention also relates to a structure comprising a metallic substrate and such a coating, and also to its use in the aeronautical or aerospace field and to the process for preparing it. |
