Abstract
A process of fabricating a shield, a process of preparing a component, and an erosion shield are disclosed. The process of fabricating the shield includes forming a near-net shape shield. The near-net shape shield includes a nickel-based layer and an erosion-resistant alloy layer. The nickel-based layer is configured to facilitate secure attachment of the near-net shaped to a component. The process of preparing the component includes securing a near-net shape shield to a substrate of a component.
Claims12
A fabrication process comprising:
- forming a near-net shape shield to a near-net shape within a die, the near-net shape having a geometry and a size requiring little or no machining or processing;
- wherein the near-net shape shield includes a nickel-based layer and an erosion-resistant alloy layer positioned at least partially on the nickel-based layer;
- wherein, prior to attachment to a component, the nickel-based layer is configured to facilitate secure attachment of the near-net shape shield to a surface of the component;
- and
- wherein the geometry of the near-net shape comprises at least one feature selected from the group consisting of cavities, protrusions, gaps, and combinations thereof.
