Title: Innovations of Donald Eugene Williams, Jr.
Introduction
Donald Eugene Williams, Jr. is a notable inventor based in Loveland, Ohio, with a significant contribution to the field of laser shock peening. He holds three patents that showcase his innovative approach to enhancing the performance and durability of materials, particularly in the aerospace industry.
Latest Patents
One of his latest patents is titled "Varying fluence as a function of thickness during laser shock peening." This invention describes a method for simultaneously laser shock peening opposite surfaces of an article, such as a gas turbine engine airfoil, using oppositely aimed laser beams. The method allows for varying surface fluence based on the thickness of the article, optimizing the treatment process. The fluence is calculated as the thickness multiplied by a volumetric fluence factor, which is maintained constant across the peening surfaces. The volumetric fluence factor typically ranges from about 1200 J/cm² to 1800 J/cm², with a more specific focus around 1500 J/cm². The energy of the laser beam can be adjusted through a computer program that controls the firing of the laser.
Another significant patent is the "System and method for controlling laser shock peening." This invention outlines a laser shock peening system that includes a workpiece held by a workholding fixture. The system features a laser source that emits multiple laser beam pulses onto the workpiece, along with an absorptive layer that absorbs these pulses. Additionally, a transparent constraining layer is positioned between the laser source and the absorptive layer, directing reflected laser-generated shock waves back into the workpiece. A transducer is also included to detect multiple acoustic signals emitted from the workpiece.
