<div class="htmlview paragraph">Nanohardness measurements performed in an SFM (Scanning Force Microscope) are compared with macrohardness data obtained by conventional means. Nanohardness provides detailed information about material hardness on a sub-micron length scale, contributing valuable insights commutator and brush wear fuel pump simulation test. For consisting of harder component dispersed softer matrix, nanohardness show the both components. The observed rates cannot be explained satisfactorily without this additional nanoscale information. expected to prove useful variety tribological systems.</div>
