The method is disclosed for coating or impregnating a metal tool with a metal oxide to render the metal part more resistant to liquid metal attack or micro- welds. The method includes the steps of applying a liquid metal carboxylate composition, or a solution thereof, to a substrate material, and exposing the substrate to an environment that will cause vaporization or dissipation of any excess carboxylic acids in the liquid metal carboxylate composition while the metal carboxylates are being converted to metal oxides.
L'invention porte sur un procédé de revêtement ou d'imprégnation d'un outil métallique avec un oxyde métallique afin de conférer à la pièce métallique une plus grande résistance à l'attaque du métal liquide ou aux micro-soudures. Le procédé consiste à appliquer une composition de carboxylates métalliques liquides ou une solution de celle-ci, sur un matériau de substrat, et exposer le substrat à un environnement qui va provoquer la vaporisation ou la dissipation d'acides carboxyliques excédentaires quelconques dans la composition de carboxylates métalliques liquides, les carboxylates métalliques étant transformés en oxydes métalliques.
