 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.
