UV curable overlays for laser peening

An apparatus for laser shot peening, comprising:

• a material applicator for applying an energy absorbing material onto a workpiece to create a coated portion;
• a curable resin applicator for applying a curable resin to said energy absorbing material on said workpiece;
• a laser to provide a laser beam through the resin to create a shockwave on the workpiece;
• a positioning mechanism to selectively position the workpiece relative to said material applicator, said resin applicator, and said laser;
• and
• a control unit operatively associated with each of said applicators and said laser, to control the operation and timing of each said applicator and said laser.

An apparatus for laser shot peening, comprising:

• a material applicator for applying a mixture of an energy absorbing material and a curable onto a workpiece to create a coated portion;
• a transparent overlay applicator for applying a transparent overlay to said mixture of said workpiece;
• a laser to provide a laser beam through the mixture to create a shockwave on the workpiece;
• a positioning mechanism to selectively position the workpiece relative to said material applicator and said laser;
• and
• a control unit operatively associated with said applicator and said laser, to control the operation and timing of said applicator and said laser.
