Title (EN) PUMPS FOR HOT AND CORROSIVE FLUIDS
(FR) POMPES POUR FLUIDES CHAUDS ET CORROSIFS
Abstract:
(EN) A pump for pumping molten metal or molten salt, said pump comprising at least one component manufactured of a substrate and coated with one or more wear and erosion resistant surface layers,wherein said substrate is provided with at least one intermediate binding layer and one outer layer, and said outer layer comprises at least one refractory oxide.
(FR) Cette invention concerne une pompe pour pomper un métal fondu ou un sel fondu, ladite pompe comprenant au moins un composant fabriqué à partir d'un substrat et revêtu d'une ou plusieurs couches de surface résistant à l'usure et à l'érosion, ledit substrat étant pourvu d'au moins une couche de liaison intermédiaire et d'une couche extérieure, et ladite couche extérieure comprenant au moins un oxyde réfractaire.
