1. A method for treating a component using a system comprising a controller configured to control operation of a laser applicator, a coating applicator, and a sensor array, wherein the laser applicator, the coating applicator, and the sensor array are arranged on a treatment arm, the method comprising:
scanning a surface to be treated of the component using the sensor array;
cleaning the surface to be treated using the laser applicator;
applying a new coating to the surface to be treated using the coating applicator; and
monitoring the cleaning and applying operations using the sensor array during the cleaning of the surface and applying the new coating; and
performing an active feedback control using the controller based on the monitoring during the cleaning of the surface and applying the new coating, wherein the active feedback utilizes physics-based models to control the laser applicator during the cleaning and the coating applicator during the coating.
