Short summary
Surface roughness has the greatest impact on the erosion wear of the rotor blade, followed by the stator blade, with the least on the guide blade. As surface roughness increases, the maximum wear rate rises and the concentrated erosion wear area expands, while its location does not shift significantly. The results can provide a basis for the erosion wear assessment of compressor blades at different service stages.
