Abstract

The aim of this study has been to investigate the rolling contact behaviour of plasma nitrided and duplex treated (plasma nitrided and diamond-like carbon (DLC)) EN40B steel under overloading and intermittent lubricating conditions using the acoustic emission technique (AE). The signal amplitude and energy were monitored and related to cracking and delamination events observed from scanning electron micrographs. AE technique was found to be capable of detecting cracking and delamination on both surface treatments, proving to be a useful tool for monitoring rotating machinery condition effectively.
