Abstract
Polycrystalline diamond (PCD) was originally developed in the 1970s for use in tooling. During manufacture, a transition metal catalyst, usually cobalt, is introduced to moderate the sintering pressures and temperatures. However, the cobalt binder remains within the PCD microstructure and plays a key role in crack nucleation and propagation. Here, the wear of PCD is studied using solid particle erosion at ambient and high temperatures.
