A method of treating the surface of a substrate by thermally spraying large size particles, > 10 micrometers, of a composition such as a metal hydroxide, carbonate, or nitrate directly onto the substrate whereby a small size particle coating, < 5 microns and more particularly < 3, is formed on the substrate, enhancing the surface area and porosity properties of the substrate, and substrates with metal oxide surfaces produced thereby.
L'invention concerne un procédé pour traiter la surface d'un substrat par pulvérisation thermique directement sur le substrat de particules de grande taille, > 10 micromètres, d'une composition telle qu'un hydroxyde, un carbonate ou un nitrate de métal. Un revêtement de particules de petite taille, < 5 microns et notamment < 3, se forme alors sur ledit substrat, améliorant la zone superficielle et les propriétés de porosité de ce dernier. La présente invention porte également sur des substrats à surfaces d'oxyde métallique fabriqués selon ce procédé.
