中文摘要	To find engineering material which has better erosion resistance, the formation of ripples and erosion on the metal material surfaces in a centrifugal slurry pump was investigated in laboratory tests using a sand-water slurry pot tester. The ripple formation was influenced by the flow conditions, the impact angle of the solid particles and the particle size. Ripple formation was also observed in laboratory tests with structural steel (40#) and brittle ceramics (Si/sub 3/N/sub 4 /). The ripple profile on the structural steel surface was similar to that on the high chrome cast iron (Cr/sub 26/) used in the slurry pumps. Ripples also formed on the eroded surfaces of materials tested in the sand-water slurry pot when the slurry impacted the surfaces at 90 degrees . The ripple wavelengths on the ceramic surfaces, which were influenced by the mechanical properties and material grain size, were less than those on the metallic surfaces.
