Measurements of specific energies for erosive wear using a Coriolis erosion tester

Measurements of erosion and calculations of specific energies for material removal have been made using the Coriolis slurry erosion tester. An analyti cal model used for the calculation of the specific energy for material remo val is based on a summation of the work done in particle-target friction by every particle passing over the specimen, assuming a value for the particl e-specimen coefficient of friction and using experimental wear volume data as input. Results on aluminum and two steels are presented as well as the v ariation of wear with velocity and slurry concentration. The Coriolis test is very rapid and is suitable for the assessment of the wear resistance of a wide range Of materials, including hard metals and elastomers Thr test si mulates well erosion conditions in equipment in which slurry flows across t he material surface such as slurry pumps, pipelines and cyclones.
