During my PhD I researched the thermomechanical wear processes in polycrystalline diamond (PCD) with specific interest in the road planing application. The aim of the research was to understand the wear mechanism in PCD compacts and how wear is affected primarily by temperature, but also by grain size, sintering conditions, surface stress state and binder content. To date, a number of solid particle erosion experiments have been performed on a range of PCD compacts.

To study the effects of temperature, the Cavendish erosion facility has been redeveloped to facilitate erosion at substrate temperatures of up to 700 degrees Celsius. Operation on PCD and other materials has been performed. Erosion at temperatures below ambient has also been developed and performed on PCD and 316 Stainless Steel.
