Adhesive and abrasive wear are the two
main mechanisms of mechanical wear. Tribological
properties between these wear mechanisms are very
different. Since wear transition could be an obstacle to
running machineries, it is important to identify the
changes in wear state. In this study, to detect wear
transition, changes in the frequency spectrum of acoustic
emission (AE) signals were examined by the friction and
wear experiments using metal pin and abrasive paper. It
was found that wear transition could be identified from
the occurrence of high frequency AE signals.
