摘要： A laser shock processing treatment is employed to condition the mating surfaces of various fastener elements, such as screws, bolts, splines, keys, and keyways. In a screw, for example, the threaded surface is laser shock processed to form laser shock processed surfaces at the thread root portion of the screw. Regions of compressive residual stresses imparted by laser shock processing are thereby formed and extend into the screw body from the laser shock processed surfaces. In a keyway, for example, the keyway surface is laser shock processed to form laser shock processed surfaces within the keyway. Regions of compressive residual stresses imparted by laser shock processing are thereby formed and extend into the keyway body from the laser shock processed surfaces. The compressive residual stress regions enhance the rigidity and torsional stiffness of the fastener elements and improve their fatigue properties.

摘要： A method and apparatus for increasing the effectiveness and efficiency of laser shock processing of a solid material. The method includes applying an energy absorbing coating to a portion of the surface of a solid material, applying an ultraviolet curable resin to the coated portion of the surface of the solid material, applying an ultraviolet light to the curable resin to form a pellicle over the energy absorbing coating on the surface of the solid material, and applying a transparent overlay to the pellicular portion of the solid material. A pulse of coherent laser energy is directed to the coated portion of the solid material to create a shockwave. After the pulse of coherent energy is directed to the solid material, a high-speed jet of fluid may be directed to the coated portion of the solid material to remove the remaining coating from the solid material.

摘要： A method and apparatus for quality control of laser shock processing. The method includes measuring emissions and characteristics of a workpiece when subjected to a pulse of coherent energy from a laser. These empirically measured emissions and characteristics of the workpiece are correlated to theoretical shock pressure, residual stress profile, or fatigue life of the workpiece. The apparatus may include a radiometer or acoustic detection device for measuring these characteristics.

摘要： A laser shock processing treatment enables a selectively adjustable and customized compressive residual stress distribution profile to be developed within a workpiece by tailoring the size and shape of the laser beam spots. One peening operation applies to the workpiece a first pattern having relatively large laser beam spots and then applies a second pattern having relatively small laser beam spots. The composite use of such small and large beam spots enables the stress distribution profile to be tailored to the part specifications. The large beam spots maximize the depth of compressive residual stress in the part, while the small beam spots optimize the surface compressive residual stresses of the part. The use of small spot beam patterns allows untreated or improperly processed areas to be laser peened.
