1. A rotary machine, comprising:
a stator;
a rotor configured to rotate with respect to the stator, the rotor being arranged with the stator at a rotor-stator interface and defining a rotor face;
a seal assembly at the rotor-stator interface, the seal assembly comprising at least one seal and a groove formed into the rotor at the rotor-stator interface; and
a removable insert positioned within the groove of the seal assembly and defining at least a portion of the rotor face,
wherein, during operation of the rotary machine, if the rotor and the stator make undesirable contact at the rotor-stator interface, the removable insert becomes damaged to prevent damage from occurring to the rotor and the stator.
