Abstract

Methods and systems for treating components are described. The methods include using a system having a controller, a laser applicator, a coating applicator, and a sensor array. The laser applicator, the coating applicator, and the sensor array are arranged on a treatment arm that is controlled by the controller. The method includes scanning a surface to be treated of the component using the sensor array, cleaning the surface to be treated using the laser applicator, defining surface texture patterns, applying laser texturing, and applying a new coating to the surface to be treated using the coating applicator.

First claim

What is claimed is:

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.

2. The method of claim 1 , wherein the applying of the new coating comprises an ultrasonic spray application.

3. The method of claim 1 , wherein the cleaning is performed using a pulsed laser.

4. The method of claim 1 , further comprising removing an existing coating on the component, using the laser applicator, prior to the cleaning.

5. The method of claim 4 , wherein the cleaning is performed using a first energy application of the laser applicator and the removing of the existing coating is performed using a second energy application of the laser applicator that is different from the first energy application.

6. The method of claim 4 , further comprising texturing the surface to be treated, using the laser applicator, after the cleaning and before the applying of the new coating.

7. The method of claim 6 , wherein the cleaning is performed using a first energy application of the laser applicator and the texturing of the surface to be treated is performed using an energy application of the laser applicator that is different from the first energy application.

8. The method of claim 1 , further comprising curing the new coating using the laser applicator.

9. The method of claim 8 , wherein the cleaning is performed using a first energy application of the laser applicator and the curing of the new coating is performed using an energy application of the laser applicator that is different from the first energy application.

10. The method of claim 1 , further comprising texturing the new coating using the laser applicator.

11. The method of claim 10 , wherein the cleaning is performed using a first energy application of the laser applicator and the texturing of the new coating is performed using an energy application of the laser applicator that is different from the first energy application.

12. The method of claim 1 , wherein the cleaning comprises applying a first energy application from the laser applicator to clean the surface to be treated, the method further comprising:
removing a coating on the component by applying a second energy application that is different from the first energy application, after the scan and after the cleaning; and
curing the new coating by applying a third energy application that is different from the first energy application and the second energy application.

13. The method of claim 12 , further comprising:
texturing the surface to be treated by applying an additional energy application after the removing of the coating and prior to applying the new coating, wherein the additional energy application is different from the first energy application, the second energy application, and the third energy application.

14. The method of claim 12 , further comprising:
texturing the new coating by applying an additional energy application after applying the new coating, wherein the additional energy application is different from the first energy application, the second energy application, and the third energy application.

15. A system for treating a component, the system comprising:
a treatment arm having a laser applicator, a coating applicator, and a sensor array; and
a controller in operable communication with each of the laser applicator, the coating applicator, and the sensor array,
wherein the controller is configured to control the laser applicator and the coating applicator to perform a treatment operation of a surface of the component in response to information obtained from the sensor array, wherein the treatment operation comprises:
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;
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 utilizing physics-based models to control the laser applicator and the coating applicator.

16. The system of claim 15 , wherein the laser applicator is a pulsed laser applicator and the coating applicator is an ultrasonic spray applicator.

17. The system of claim 15 , wherein the treatment operation further comprises:
removing an existing coating on the component prior to the cleaning using the laser applicator.

18. The system of claim 17 , wherein the cleaning step is performed using a first energy application of the laser applicator and the removing of the existing coating is performed using a second energy application of the laser applicator that is different from the first energy application.

19. The system of claim 17 , wherein the treatment operation further comprises at least one of:
texturing the surface to be treated after the cleaning and before the applying of the new coating; and
texturing the new coating after application thereof.

20. The system of claim 19 , wherein the cleaning step is performed using a first energy application of the laser applicator and the texturing of the surface to be treated is performed using an energy application of the laser applicator that is different from the first energy application.
