Abstract
A method for manufacturing a casted article is presented. The method includes steps of forming a casted article by a liquid metal cooled directional solidification process, removing a metallic material from a surface of the casted article and inspecting the surface of the casted article. The surface of the casted article is inspected for the presence of the metallic material by exposing the surface to a visualization reagent. A system for manufacturing the casted article is also presented.
Claims24
A method, comprising steps of:
- forming a casted article by a liquid metal cooled directional solidification process;
- removing a metallic material from a surface of the casted article;
- and
- inspecting for the presence of the metallic material on the surface of the casted article by exposing the surface to a visualization reagent.
A method, comprising:
- filling a mold with a molten metal;
- immersing the mold into a cooling metallic liquid progressively, to cause a solidification interface to pass through the molten metal;
- recovering a casted article from the mold;
- removing a metallic material from a surface of the casted article;
- and
- inspecting for the presence of the metallic material on the surface of the casted article by exposing the surface to a visualization reagent.
A system, comprising:
- a heating furnace at a temperature above the liquidus temperature of a metal within a mold;
- a liquid cooling bath comprising a cooling metallic liquid;
- a bath comprising an aqueous composition to remove a metallic material from a surface of a casted article;
- a unit to expose at least a portion of the casted article to a visualization reagent;
- and
- a visualization aid for observing a response of the visualization reagent.
