  • Process for making ceramic molds having a metal oxide barrier for casting and directional solidification of superalloys
    Patent number: 4031945
    Abstract: At least one element of a superalloy cast into a refractory oxide-silica investment mold is oxidized to form a metal oxide barrier layer at the mold-metal interface to permit directional solidification of the cast superalloy at elevated temperatures without metal-mold reaction.
    Type: Grant
    Filed: April 7, 1976
    Date of Patent: June 28, 1977
    Assignee: General Electric Company
    Inventors: Michael F. X. Gigliotti, Jr., Charles D. Greskovich
  • Process for forming a barrier layer on ceramic molds suitable for use for high temperature eutectic superalloy casting
    Patent number: 3972367
    Abstract: A method of forming a metal oxide barrier layer at the interface between a refractory oxide-silica investment mold and a contained metal superalloy includes the firing of the mold or the mold-metal system, in a controlled prevailing atmosphere having a predetermined amount of oxygen therein. The barrier layer enables directional solidification of the contained superalloy at elevated temperatures to occur without metal-mold reaction.
