PROBLEM TO BE SOLVED: To provide a casting mold suitable for directional solidification processes using a liquid cooling bath and composed in such a manner that, during directional solidification processes, the reaction between a metal coolant and the surface of a cast metal is prevented or delayed. SOLUTION: The casting mold 10 suitable for directional solidification processes using a liquid cooling bath includes a graded facecoat structure 12 on a mold body. The graded facecoat structure includes an innermost layer 14 and a delamination layer 18, wherein the delamination layer fractures upon cooling of the molten metal so as to separate the mold body from the innermost layer, which remains in contact with or in close proximity to the metal being cast. Also disclosed are directional solidification processes. COPYRIGHT: (C)2010,JPO&INPIT |
