Abstract
A severe-mild wear transition was found in Alrubbing. Aluminium and zinc are both non-transition metals, hence mild wear has never been observed in AlAl and ZnZn rubbings under dry sliding conditions in air. However, mild wear was found during aluminium pin and zinc disk rubbing. From the measurement of current-voltage characteristics on the zinc disk surface, it was determined that the transition of wear mode from severe to mild wear occurred due to the formation of a semiconducting material in the wear track during sliding. The occurrence of mild wear in AlZn rubbing is discussed in reference to the formation of semiconducting material on the sliding surface. Further, the occurrence of mild wear in AlZn rubbing through the formation of semiconducting materials was endorsed by the wear of semiconductor silicon in sliding contact with metals.
