Abstract: | The debris produced in vibration cavitation tests of three kinds of carbon steel were collected.Their geometric features were analyzed quantitatively and observed respectively by a profilometer and a scanning electronic microscope(SEM) with reference to the investigation of the cavitation damaged surface by SEM and X-ray diffraction(XRD) .It was found that among the debris produced in all cavitation erosion stages,more than 45%were platelets because of the occurrence of dislocation and cleavage fracture,and... |
