CA 2657782

High performance coated metal compositions resistant to metal dusting corrosion and methods of providing such compositions are provided by the present invention. The coated metal compositions are represented by the structure (PQR), wherein P is an oxide layer at the surface of (PQR), Q is a coating metal layer interposed between P and R, and R is a base metal. P includes alumina, chromia, silica, mullite or mixtures thereof. Q includes Ni and Al. R is selected from the group consisting of carbon steels, low chromium steels, ferritic stainless steels, austenetic stainless steels, duplex stainless steels, Inconel alloys, Incoloy alloys, Fe-Ni based alloys, Ni-based alloys and Co-based alloys. Advantages exhibited by the disclosed coated metal compositions include improved metal dusting corrosion resistance at high temperatures in carbon-supersaturated environments having relatively low oxygen partial pressures. The coated metal compositions are suitable for use in syngas generation process equipment.

Compositions métalliques de revêtement haute performance résistant à la corrosion par effusement métallique et procédés d'élaboration de ces compositions. Les compositions sont représentées par la structure (PQR), P étant une couche d'oxyde à la surface de (PQR), Q est une couche de revêtement métallique entre P et R, et R est un métal de base. P comprend alumine, chrome, silice, mullite ou des mélanges correspondants. Q comprend Ni et Al. R est sélectionné dans le groupe des aciers au carbone, aciers inoxydables ferritiques, aciers inoxydables austénitiques, aciers inoxydables duplex, alliages Inconel, alliages incoloy, alliages à base de Fe-Ni, alliages à base de Ni et alliages à base de Co. Les avantages de ces compositions sont une amélioration de la résistance à la corrosion par effusement métallique aux températures élevées dans des environnements supersaturés en carbone à pressions partielles d'oxygène relativement faibles. Elles sont appropriées à une utilisation dans les équipements de traitement pour la production de gaz de synthèse.
