Abstract
In some examples, a method for making a refractory component includes depositing carbon on a surface of a refractory substrate. The carbon fills surface voids on the surface of the refractory substrate. A melting point of the refractory substrate is greater than or equal to about 1500 degrees Celsius (° C.). The method includes applying a metal slurry to a surface of the refractory substrate following the deposition of the carbon and reacting a metal of the metal slurry with the carbon to form a metal carbide phase within the surface voids of the refractory substrate.
Claims20
A method for making a refractory component, the method comprising:
- depositing carbon within surface voids of a refractory substrate, wherein a melting point of the refractory substrate is greater than or equal to about 1500 degrees Celsius (° C.);
- applying a metal slurry to the refractory substrate following the deposition of the carbon;
- and
- reacting a metal of the metal slurry with the carbon to form a metal carbide phase within the surface voids of the refractory substrate.
An article of a foundry system, the article comprising:
- a refractory component defining an oxidation-resistant surface configured to contact molten metal, wherein the refractory component comprises:
- a refractory substrate, wherein a melting point of the refractory substrate is greater than or equal to about 1500 degrees Celsius (° C.);
- and
- a metal carbide phase within surface voids of the refractory substrate.
