摘要： A method is for forming a periodic groove arrangement. According to the method, a base material made of metal is provided. Furthermore, the periodic groove arrangement, which includes a plurality of periodic grooves, is formed on a surface of the base material by irradiating and scanning the surface of the base material with a pulsed laser. A fuel injection system includes a nozzle hole forming part and the periodic groove arrangement formed by the method. The nozzle hole forming part includes a nozzle hole, which passes through the nozzle hole forming part and through which fuel is injected. The periodic groove arrangement is formed on an outer surface of the nozzle hole forming part.
