Modification and extension of a model for predicting the erosion of ductile materials

A statistically derived model for predicting the erosion of ductile target materials was modified and its range was extended to incorporate maximum particle velocities of approximately 3000 m/sec. The usefulness of the modified model in predicting the erosion of ductile targets by both homogeneous and heterogeneous erosive agents was assessed.It was found that soft erosive particles can produce higher erosion rates than hard particles for the same target material. It was concluded that the geometry of the particle acceleration tube employed in the erosion test facility had a significant effect on the magnitude of observed erosion rates.
