In order to clarify the mechanism of water-jet erosion, we systematically investigate the erosion-standoff-distance curves, the erosion-time curves, and detailed aspects of the eroded surface for two typical types of nozzles, i.e., conical and cylindrical nozzles. Clearly, the erosion-time curves are markedly different at the 1st peak, at the valley and at the 2nd peak. Hence, the mechanism of erosion is significantly changed with an increase in the standoff distance x.
