The wear of monolithic carbon electrical brushes will be                        studied.  Analytical modeling of the particle ejection                          theory of brush wear will be compared with experimentally                       obtained results.  The experimental apparatus will make it                      possible to observe the development and movement of hot                         spots in the contact area, generated due to both frictional                     heating and heating from the electrical current passing from                    the brush surface to the matching surface.  The effect of a                     number of test parameneters will be determined and the results                  used to validate and improve the model.
