Polycrystalline diamond
materials have a variety of applications, mainly as cutting tools for machining
non-ferrous metals and non-metallic materials. A significant application of PCD
is in the oil and gas industry for rock drilling operations. Other important
areas, such as mining, have yet to reach their full potential. The unique
combination of hardness, toughness and strength makes components containing PCD
an excellent solution for a variety of rock-drilling operations. Furthermore,
the extraordinary hardness of diamond, it’s very high thermal conductivity and
low friction coefficient make it an ideal tool material for the machining of
wood and wood-based composites. Therefore, there are a number of reasons for
the superior performance of PCD and diamond-coated carbides over tools made of
cemented carbides, such as larger abrasion resistance, improved ability of
machining to smaller tolerances and lowered acoustic emissions. In order to
accurately predict the behavior of a PCD cutting tool under typical operating
conditions encountered during drilling operations, knowledge about the range of
mechanical and fracture properties is crucial. There has been very little
research conducted in the area of fracture of super hard materials. Lack of
available mechanical and fracture properties in addition to a poor
understanding of the fracture process results in relatively high and
unnecessary financial losses associated to use of these materials. Therefore,
establishing some sort of standard for ranking PCD materials is essential to
the development of new improved materials.
