Protective coatings for molten metal devices
First Claim
1. A protected component for use in a molten metal bath, the protected component including a non-coated component and a protective coating and made by the process of:
- (a) placing a protective coating on a non-coated component, wherein a space exists between the non-coated component and the protective coating;
(b) injecting uncured cement into the space; and
(c) allowing the uncured cement to cure, thus adhering the non-coated component to the protective coating.

Abstract
Disclosed are components covered with a protective coating for use in a molten metal bath (or comparable environment) and devices including such components. The protective coating is preferably a ceramic sleeve adhered to a non-coated component by cement. A component with the protective coating is more resistant to degradation in molten metal than is the component without the coating, and may be manufactured by the process of (a) placing the protective coating over the non-coated component, and (b) injecting cement into the space between the non-coated component and protective coating, wherein at least some of the cement is injected through a passage in either the non-coated component or the protective coating.
