Method of Forming a Turbine Engine Component Having a Vapor Resistant Layer
First Claim
1. A method of forming a turbine component having a vapor resistant layer, comprising:
- providing an inner tool and an outer tool, wherein the inner and outer tools define a mold for forming a turbine component;
applying a vapor resistant layer to the inner tool;
applying a ceramic insulation layer over the vapor resistant layer in the mold;
partially firing the vapor resistant layer and the ceramic insulation layer to form a bisque turbine component; and
removing the outer tool.

Abstract
A method of forming a turbine component that includes a ceramic matrix composite-ceramic insulation composite with a vapor resistant layer is disclosed. The method includes providing an inner tool and an outer tool, wherein the inner and outer tools define a mold for forming a turbine component. A vapor resistant layer can be applied to the inner tool, and a ceramic insulation layer can be applied over the vapor resistant layer in the mold. The vapor resistant layer and the ceramic insulation layer can be partially fired to form a bisque turbine component, and the outer tool can be removed. The inner tool can include a transitory material. A layer of ceramic matrix composite material can be applied to the outside of the bisque turbine component to form a component, and the component can be fired to form a turbine component.
