Experimental Study of Polycrystalline Diamond Compacts (PDCs) Wear Mechanisms.
MetadataShow full item record
PDCs are among the most commonly used materials on cutting and drilling tools for rock fragmentation. However, they show inconsistent performance in hard rocks with excessive wear and chipping. This research is an experimental study of wear mechanism of PDCs in hard rocks with primary focus on polishing and chipping. This research showcases the limitations of laboratory wear tests due to machine dependency. It also challenges commonly used wear parameters, which disregards associated wear mechanisms.

Amoun, S.; Sharifzadeh, Mostafa ; Shahriar, K.; Rostami, J. (2015)Full-face shielded tunnel boring machines (TBM) including earth pressure balance (EPB) shields have been used almost exclusively for soft ground tunneling because of the many advantages the offer in comparison to the ...
Validity of an automated algorithm to identify waking and in-bed wear time in hip-worn accelerometer data collected with a 24 h wear protocol in young adultsMcVeigh, Joanne; Winkler, E.; Healy, Genevieve; Slater, J.; Eastwood, Peter; Straker, Leon (2016)Researchers are increasingly using 24 h accelerometer wear protocols. No automated method has been published that accurately distinguishes 'waking' wear time from other data ('in-bed', non-wear, invalid days) in young ...
