Fundamental Studies on Cavitation Erosion : Observation of the Eroded Surface by Scanning Electron Microscope

抄録

In the present paper, cavitation erosion of several structure materials is studied by means of continuous observations by a scanning electron microscope, etc. Erosion damages are affected by the grain orientation on testing surfaces as well as the crystal structure of test materials. On the whole, erosion resistance decreases according to an increase in the plastic deformation of grains.
