Abstract
A casting core assembly has: a first ceramic piece including a projecting post; a second ceramic piece including a socket encircling the post; and a ceramic filler material between the post and the socket. At least one of: in axial section at at least one location the post has a lateral protrusion of at least 15 micrometers relative to a location proximal thereof; and in axial section at at least one location socket has a lateral recess of at least 15 micrometers relative to a location outboard thereof.
Claims22
A casting core assembly comprising:
- a first ceramic piece including an integrally molded projecting post;
- a second ceramic piece including a socket encircling the post;
- and
- a ceramic filler material between the post and the socket,
- wherein at least one of:
- in axial section at at least one location the post has:
- a lateral protrusion of at least 15 micrometers relative to a location proximal thereof;
- and
- in axial section at at least one location the socket has:
- a lateral recess of at least 15 micrometers relative to a location outboard thereof.
A casting core assembly comprising:
- a first ceramic piece including an integrally molded projecting post;
- a second ceramic piece including a socket encircling the post;
- and
- a ceramic filler material between the post and the socket,
- wherein at least one of the post and the socket has a full annular recess into which the ceramic filler material extends to axially backlock said at least one to the ceramic filler material.
A casting core assembly comprising:
- a first ceramic piece including an integrally molded projecting post;
- a second ceramic piece including a socket having an axis;
- and
- a ceramic filler material between the post and the socket,
- wherein the ceramic filler is axially backlocked to the post and the socket to prevent nondestructive axial extraction of the post from the socket.
