One problem in fossil fuel conversion is the wear and erosion of equipments such as combustors. Studies were conducted to evaluate the response of annealed 1100 aluminium to single and multiple erosive particle impacts. The 30{degree} incidence angle multiple particle part impact conditions ranged from that necessary to produce damage characteristic of the incubation period through that require to develop the steady state condition. Single impacts on samples were done at room temperature by spherical particles with an incidence angle of 30{degree}. A mechanical properties microprobe was used to measure the hardness at the bottom of the craters formed by single impacts and in the material below the crates. A characteristic ripple structure developed on the surface with increasing dose. For the incubation period samples, the increase of deformation of the subsurface layers was studied using tapersectioning techniques in conjunction with a mechanical properties microprobe while normal sectioning was used for the steady state samples. Distinct differences were observed in the hardness profiles beneath crests and valleys which form the ripple structure.
