Abstract
It is well known that acoustic emission (AE) is the emission of elastic stress waves resulting from the deformation and fracture of materials. This paper deals with a monitoring technique of the friction and wear behavior applied with the AE. Moreover, investigation was carried out about the prediction of unusual phenomenon of the friction and wear. The results are summarized as follows: (1) A little discrepancy of the friction and wear behavior can be detected sensitively by AE signals. (2) AE signals are used effectively in monitoring the run out state of lubricating oil film into frictional surfaces. (3) AE signals can be used for prediction of unusual phenomenon such as seizure.
