A review of acoustic emission as a biotribological diagnostic tool

ABSTRACT

Acoustic emission (AE) testing has been used in the detection of the onset and progression of mechanical flaws. It has also proven advantageous in the tribological assessment of mechanical systems and human joints as well as for implant condition monitoring. Current modes of diagnosing implant failures are becoming less effective and time consuming calling for the development of a more effective and dynamic diagnostic method. This review aims to provide an overview of the current tribological applications of AE and to highlight how this can be instrumental in the development of a more effective failure diagnosis method. It can be concluded that AE has potential capabilities as a tool for monitoring the tribological phenomenon of artificial joints which would not only allow for a more effective way of diagnosing implant failures but also for diagnosing natural joint diseases such as back pain and arthritis.
