| 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. | ||||
