Mechanisms of Erosion of a Ductile Material by Solid Particles

Source

Erosion of flat plates and tubular test specimens by spherical 270-μm steel shot showed appreciable differences in the amount of material removed, depending on the condition of the steel shot used. Ductile shot removed considerably less material than brittle or more frangible shot. In addition, lower-velocity exponents were obtained for the tougher, more ductile abrasive.

The evidence presented here supports the view of Tilly that erosion by frangible particles may be viewed as a two-stage process. According to this view, the first stage is due to surface indentation by the particle, forming vulnerable lips around the crater, and the second is due to removal of these lips by radially projecting particle fragments.
