A method for stripping ceramic from a component, comprising:
- applying a liquid to a ceramic coating of an outer surface of the component;
- and
- directing a plurality of laser pulses at the ceramic coating with the applied liquid in order to spall the ceramic coating from the component.
A system for stripping ceramic from a component, the system comprising:
- At least one of a gripper or a nest configured to retain the component;
- a laser generator configured to generate a plurality of laser pulses;
- a liquid configured to be applied to a ceramic coating of an outer surface of the component;
- and
- an actuator coupled to the at least one of the gripper or nest or the laser generator and configured to at least one of move the gripper or nest relative to the laser generator or to move the laser generator relative to the gripper or nest.
