文摘On a specially designed ball on disc type tribometer, both the friction coefficients and the self generated voltages (SGVs) for SUJ2/Al and SUJ2/Cu dry rubbing pairs were measured; and the correlation between SGV and friction coefficient was ascertained during test. The relationship between the SGVs and the tribological characteristics shows that monitoring SGVs of rubbing pairs can be used as a new on line means for evaluating wear of metallic materials. Moreover, this method has an advantage over the electrical resistance method, which needs externally applied voltage and may introduce some influences on the surface states.
