Methods of manufacturing casted articles, and systems

摘要

A method (10) for manufacturing a casted article (62) is presented. The method (10) includes steps of forming a casted article (62) by a liquid metal cooled directional solidification process (12), removing a metallic material (66) from a surface (64) of the casted article (62), (24) and inspecting the surface (64) of the casted article (62), (26). The surface (64) of the casted article (62) is inspected for the presence of the metallic material (66) by exposing the surface (64) to a visualization reagent (110). A system (60) for manufacturing the casted article (62) is also presented.
