Title (EN) FUMED METAL OXIDES FOR INVESTMENT CASTING
(FR) OXYDES MÉTALLIQUES SUBLIMÉS POUR MOULAGE DE PRÉCISION
Abstract: front page image
(EN)Investment casting shells are manufactured by incorporating fumed metal oxide dispersions, or doped fumed metal oxides as a binder into the casting shell. The investment casting shells containing the fumed metal oxides have improved characteristics, such as increased strength and a reduced surface roughness.
(FR)L'invention concerne des coquilles de moulage de précision fabriquées en incorporant des dispersions d'oxyde métallique sublimé, ou des oxydes métalliques sublimés dopés comme liant dans la coquille de moulage. Les coquilles de moulage de précision contenant les oxydes métalliques sublimés ont des caractéristiques améliorées, telles qu'une résistance mécanique accrue et une rugosité de surface réduite.
