A stator vane is provided that includes an airfoil and a coating. The airfoil comprises a polymer matrix fiber composite having a melting point, glass transition temperature, or maximum exposure temperature that is less than about 150° C. The coating is formed over the airfoil and comprises a material that is more erosion-resistant than the polymer matrix fiber composite, where the material is the selected from a group of constituents consisting of titanium, chromium, vanadium, and zirconium, and nitrides, carbides, mixed carbonitrides, oxides, oxynitrides, oxycarbides, and oxycarbonitrides thereof. Methods for making the stator vane are provided as well.

I claim: 1. A method of forming a coating on a stator vane, the method comprising the steps of: placing the stator vane in a vacuum chamber, while maintaining the stator vane at a temperature substantially equal to or below a predetermined temperature, the stator vane comprising a polymer matrix fiber composite having a melting point, glass transition temperature, or maximum exposure temperature that is less than about 150° C., and the predetermined temperature being less than the melting point, glass transition temperature, or maximum exposure temperature; and forming a coating over the stator vane, while the stator vane temperature is maintained substantially equal to or below the predetermined temperature, the coating comprising a material that is more erosion-resistant than the polymer matrix fiber composite, wherein the material is selected from a group of constituents consisting of titanium, chromium, vanadium, and zirconium, and nitrides, carbides, mixed carbonitrides, oxides, oxynitrides, oxycarbides, and oxycarbonitrides thereof and the material has a melting point that is higher than 150° C. 2. The method of claim 1, wherein the step of maintaining comprises contacting the stator vane with a fixture having channels formed therethrough, and flowing a gas or liquid through the channels. 3. The method of claim 1, wherein the step of maintaining comprises disposing the stator vane proximate a substrate having a temperature that is substantially equal to or below the predetermined temperature, the substrate configured to receive heat radiated from the stator vane. 4. The method of claim 1, wherein the step of maintaining comprises flowing a gas over the stator vane at a pressure greater than about 1 Torr to direct heat away from the stator vane. 5. The method of claim 1, wherein the step of depositing comprises depositing the coating onto the stator vane using a sputtering process. 6. The method of claim 1, wherein the step of depositing comprises depositing the coating onto the stator vane using a chemical vapor deposition process. 7. The method of claim 1, wherein the step of depositing comprises depositing the coating onto the stator vane using a molecular beam epitaxy process. 8. The method of claim 1, wherein the step of depositing comprises depositing the coating onto the stator vane using an atomic layer deposition process. 9. The method of claim 1, wherein the step of depositing comprises depositing the coating onto the stator vane using an electron beam evaporation process. 10. The method of claim 1, wherein the step of forming a coating comprises forming a coating consisting of titanium and titanium nitride. 11. The method of claim 1, further comprising: forming a layer over the coating, while the stator vane temperature is maintained substantially equal to or below the predetermined temperature, the layer comprising a material that is more erosion-resistant than the coating. 12. The method of claim 11, further comprising: forming a nanolaminate by repeating the steps of forming a coating and forming a layer over the coating. 13. The method of claim 1, wherein the polymer matrix fiber composite comprises a carbon epoxy composite. 14. The method of claim 1, wherein the predetermined temperature is less than about 100° C. 15. A method of forming a coating on a stator vane, the method comprising the steps of: placing the stator vane in a vacuum chamber, while maintaining the stator vane at a temperature substantially equal to or below a predetermined temperature, the stator vane comprising a polymer matrix fiber composite having a melting point, glass transition temperature, or maximum exposure temperature that is less than about 150° C., and the predetermined temperature being less than the melting point, glass transition temperature, or maximum exposure temperature; forming a coating over the stator vane, while the stator vane temperature is maintained substantially equal to or below the predetermined temperature, the coating comprising a material that is more erosion-resistant than the polymer matrix fiber composite, wherein the material is selected from a group of constituents consisting of titanium, chromium, vanadium, and zirconium, and nitrides, carbides, mixed carbonitrides, oxides, oxynitrides, oxycarbides, and oxycarbonitrides thereof and the material has a melting point that is higher than 150° C.; forming a layer over the coating, while the stator vane temperature is maintained substantially equal to or below the predetermined temperature, the layer comprising a material that is more erosion-resistant than the coating; and forming a nanolaminate by repeating the steps of forming a coating and forming a layer over the coating. 16. The method of claim 15, wherein the polymer matrix fiber composite comprises a carbon epoxy composite. 17. The method of claim 15, wherein the predetermined temperature is less than about 100° C. 18. The method of claim 15, wherein the step of forming a coating comprises forming a coating consisting of titanium and and the step of forming a layer comprises forming a layer consisting of titanium nitride.
