The current understanding on the diamond machining of …

20/5/2014· Both diamond (the hardest naturally-occurring material identified to date) and silicon carbide are classified as hard and brittle [] due to their sp 3-bonded nature and shorter bond length. Under aient conditions, nitrogen is gaseous with only diatomic covalent bonds while boron, silicon and diamond (carbon) naturally form three-dimensionally covalent solids [ 2 ].
