Samples of annealed 1100 aluminum and 7075-T6 aluminum were eroded to steady-state conditions in a multiple particle erosion system. The samples were sectioned through the eroded areas, and a mechanical properties microprobe was used to measure the hardness of the material. The oblique multiple particle impacts produced a rippled surface with the hardness at the top of the wave crests approximately equal to that in the valleys. However, the total depth of hardening was significantly greater in material below the wave crests and was a function of the material for both wave crests and valleys. The depth of hardened material below the wave crest was about equal to the height of the wave plus the depth of hardening below the valley. 23 refs., 5 figs.
