Engine components and rotor groups are provided. In an embodiment, by way of example only, an engine component includes an impeller and a protective sleeve. The impeller has a bore defined by an inner surface. The protective sleeve lines the inner surface of the impeller and comprises a polymer material. In another embodiment, by way of example only, a rotor group includes an impeller, a protective sleeve, a rotor component, and a tie shaft. The impeller has a first bore defined by an inner surface. The protective sleeve lines the inner surface of the impeller and comprises a polymer material. The rotor component has a second bore, and the tie shaft extends through the first bore and the second bore.

1. An engine component, comprising: an impeller having a bore defined by an inner surface, the bore extending between a first end and a second end and having a first section and a second section, the first section having a first diameter and the second section having a second diameter that is less than the first diameter; anda protective sleeve disposed in the second section and lining the inner surface of the impeller, the protective sleeve comprising a polymer material and including a first end having a first flange extending radially outwardly therefrom and a second end having a second flange extending radially outwardly therefrom, the first flange disposed against a surface of the impeller that defines an inlet to the second section of the bore. 2. The engine component of claim 1, wherein the protective sleeve comprises a fluoropolymer material. 3. The engine component of claim 1, wherein the protective sleeve comprises a polyamide. 4. The engine component of claim 1, wherein the protective sleeve includes a slit extending along at least a portion of an axial length of the protective sleeve. 5. The engine component of claim 4, wherein the slit includes a cut in the protective sleeve. 6. The engine component of claim 4, wherein the slit forms an axially-extending gap in the protective sleeve. 7. The engine component of claim 1, wherein the protective sleeve includes an axial slit extending from a first end of the protective sleeve along a portion of an axial length of the protective sleeve. 8. The engine component of claim 1, wherein the protective sleeve includes an axial slit extending from a first end of the protective sleeve to a second end of the protective sleeve. 9. The engine component of claim 1, wherein the protective sleeve includes a plurality of axial slits extending from the first end of the protective sleeve along a portion of an axial length of the protective sleeve. 10. A rotor group comprising: an impeller having a first bore defined by an inner surface, the first bore extending between a first end and a second end and having a first section and a second section, the first section having a first diameter and the second section having a second diameter that is less than the first diameter;a protective sleeve disposed in the second section and lining the inner surface of the impeller, the protective sleeve comprising a polymer material and including a first end having a first flange extending radially outwardly therefrom and a second end having a second flange extending radially outwardly therefrom, the first flange disposed against a surface of the impeller that defines an inlet to the second section of the first bore;a rotor component having a second bore; anda tie shaft extending through the first bore and the second bore. 11. The rotor group of claim 10, wherein the protective sleeve comprises a fluoropolymer material. 12. The rotor group of claim 10, wherein the protective sleeve comprises a polyamide material. 13. The rotor group of claim 10, wherein the protective sleeve includes a slit extending along at least a portion of an axial length of the protective sleeve. 14. The rotor group of claim 10, wherein the slit includes a cut in the protective sleeve. 15. The rotor group of claim 10, wherein the slit forms an axially-extending gap in the protective sleeve.
