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).
