Title (EN) SKELETAL COLUMNAR COATINGS
(FR) REVETEMENTS COLONNAIRES A SQUELETTE
Abstract:
(EN) Skeletal columnar coatings with a well-adhered columnar structure having both intercolumn and intracolumn porosity are metallic alloys of catalytic elements and non-catalytic elements and are particularly useful in making catalytic surfaces, electroactive surfaces and self-cleaning surfaces.
(FR) Revêtements colonnaires à squelette présentant une structure colonnaire à bonne adhérence ayant une porosité tant intercolonnaire qu'intracolonnaire, qui sont des alliages métalliques d'éléments catalyseurs et d'éléments non catalyseurs et sont particulièrement utiles pour fabriquer des surfaces de catalyse, des surfaces électroactives et des surfaces autonettoyantes.
