ABSTRACT:
The invention relates to a method and apparatus for improving properties of a solid material by providing shock waves therethrough. Laser shock processing is used to provide the shock waves. The method includes applying a water based coating to a portion of the surface of the solid material and then applying a transparent overlay to the coated portion of the solid material. A pulse of coherent laser energy is directed to the coated portion of the solid material to create a shock wave. A high speed jet of fluid is directed to coated portion of the solid material at times to remove the coating from the solid material. Additionally, the method may include directing a high speed jet of fluid to the surface of the solid material to dry the solid material.
