抄録

Cavitation erosion of sintered aluminum oxide and silicon carbide was investigated by a vibratory test. The erosion of aluminum oxide originated at defects such as pores and holes, where intergranular fractures occurred. Particles were removed granule by granule. Better erosion resistance is obtained for an aluminum oxide with a smaller grain size. The erosion of silicon carbide originated around the pores. Cracklike grooves propagating through pores were observed on the eroded surface and massive particles were removed. Better erosion resistance is obtained for a silicon carbide with a smaller number and size of pores. The erosion resistance was compared with that of metals.
