Abstract: A metallic fuel system component (14, 50) includes an internal surface (52, 90) and an external surface (54, 92). The metallic fuel system component (14, 50) is made by inducing compressive residual stress in only a portion of the internal surface (52, 90) of the metallic fuel system (10) component by transmitting a laser shock wave (146) through the metallic fuel system (10) component from the external surface (54, 92) to the internal surface (52, 90).

Abstract: A electrical discharge machining apparatus (10) is disclosed. The apparatus may have an electrode (16), an actuator (22) configured to advance the electrode, and a power supply (14). The apparatus may also have a controller (12) in communication with the actuator and the power supply. The controller may be configured to negatively charge the electrode, and regulate the actuator to advance the negatively charged electrode toward a positively charged workpiece (18), thereby initiating erosion of the positively charged workpiece. The controller may also be configured to positively charge the electrode and negatively charge the workpiece to erode the electrode to a desired condition after workpiece erosion has been initiated. The controller may also be configured to continue advancing the electrode toward the workpiece after the electrode has been eroded to the desired condition.
