1. An assembly for a turbine engine, comprising:
an impeller rotor configured to rotate about a rotational axis, the impeller rotor comprising impeller rotor material;
a seal land extending axially along and circumferentially about the rotational axis, the seal land mechanically attached to and rotatable with the impeller rotor, and the seal land comprising seal land material that is different than the impeller rotor material; and
a lip seal radially engaging the seal land;
wherein a rotor bore extends axially along the rotational axis into the impeller rotor; and
wherein the seal land comprises a mount that projects axially along the rotational axis into the rotor bore, and the mount is mechanically attached to the impeller rotor.
