Abstract
A method for removing a surface coating by impinging an area of impingement of the surface coating with photon energy while simultaneously impinging the area of impingement with a cryogenic particle blast flow.
Claims20
A method of removing a surface coating from a substrate, comprising:
- a) applying energy to an area of impingement of the surface coating so as to elevate a temperature of at least a portion of the surface coating within the area of impingement to a temperature at least as high as that required to pyrolyze the surface coating;
- and
- b) while said at least a portion of the surface coating is at a temperature above that required to pyrolyze the surface coating, impinging the area of impingement with cryogenic particles.
