The project described in this report has included both computer models and experimental measurements of the rebound velocities of particles during erosion of metals. Computer models were developed for impact of both spherical and idealized two-dimensional particles. Although simplified, the models allowed predictions to be examined for a wide range of experimental conditions, particles and materials. Experimental systems were developed for the measurement of dynamic hardness, single particle rebound of spherical and angular particles, and multiple particle rebound during steady-state erosion. Comparison of experimental results with model predictions shows generally good agreement, and shows that particle rebound is largely determined by particle dynamics. The method developed for measurement of dynamic hardness from rebound velocity alone provides a more rapid unambiguous method than the more common approach in which crater dimensions must be measured after impact.
