Abstract
The effect of viscosity on the wear particles produced by vibratory
cavitation erosion tests on Al-99.92 in distilled water and glycerol-water
solutions was analyzed. Scanning electron microscope images of wear
particles during incubation period were obtained. The surface
topography examination revealed that the erosion particles were formed
by fatigue. The particles removed from glycerol-water solutions differ
from that formed in distilled water, where fatigue striations formed on
the particle surface for glycerol-water solutions and not formed for
distilled water. Therefore, the stress produced by cavitation bubbles
decreases with increase of viscosity.
