摘要：

Slurry jet tests were conducted for pure aluminum, pure copper, cast martensitic stainless steel, austenitic stainless steel and cast steel. The flow velocity of the slurry was 10 m/s, the slurry concentration was 1 mass%, and the impingement angle was 90 degrees. Moreover, the particle behavior was calculated using a commercial code for a flow analysis, STAR-CD. The relation between volume loss of material per an impact particle and erosion factors, which are impact velocity, angle, particle size and frequency, was derived from a numerical analysis of the particle behavior and the surface profile at an impingement angle of 90 degrees. The volume loss in the slurry jet test at 30 degrees or less can be predicted by using above relation. (C) 2008 Elsevier B.V. All rights reserved.
