A multilayer paint erosion indication technique to produce a highly visual and accelerated map of erosion damage occurring in a three-dimensional component model has been developed. An investigation to obtain an understanding of how the paint layers eroded as a function of a number of erosion variables was performed. It was observed that the erosion rate behaviour of paint layers as a function of angle of particle impact, velocity, time and particle loading was in good agreement with previously reported material erosion behaviour of steels and other engineering materials. These results indicate that it is possible to use the multilayer paint erosion indication technique to provide a highly visual representation of erosion damage to complex component geometries. Such baseline information on the paint layer erosion behaviour should provide an opportunity to relate erosion data from geometry based erosion maps, such as those shown in Fig. 1, to realistic engineering situations.
