Abstract
Coatings, for example polymer coatings or sol-gel coatings, including at least one layer of micrometric, individualised and mesostructured spherical particles. The particles having been created and loaded with at least one element selected from corrosion-inhibiting functional molecules and corrosion-inhibiting functional nano-objects, by a method having non-dissociable nebulization-heating steps that are continuous in a single reactor. The coatings form an anti-corrosion system, having mechanical strength and/or for coloring. The coatings are applicable, in particular, in the field of protecting light aeronautical alloys against corrosion.
