The current understanding on the diamond machining of ...
Ultra-hard brittle materials exhibit extreme hardness due to their covalent and ionic bonds. An interesting feature which all such materials share is the short sp 3 –sp 3 bond length. In general, they can be represented using the 'composition cycle' shown in figure 1 [].This cycle consists of the four elements, i.e. carbon (C), boron (B), silicon (Si) and nitrogen (N) and the combination of ...
