Conversely, if the probing stylus enters a film thick enough to have several layers of nodules so it cannot be spread laterally, or if it enters on top of a cobblestone in a single layer, then it will measure not only the real hardness of the diamond bonding, but an apparent hardness even greater because the internal compressive stress in those nodules would provide further resistance to penetration of the material by the stylus. You can download the paper by clicking the button above. Usually techniques either combine such a compression with a push of the new cluster of sp3 bonded carbon deeper into the coating so that there is no room for expansion back to separations needed for sp2 bonding; or the new cluster is buried by the arrival of new carbon destined for the next cycle of impacts. It is also being used as a coating by some weapon manufacturers/custom gunsmiths. Tooling components, such as endmills, drill bits, dies and molds often use DLC in this manner.

Its main purpose is to enlarge or increase a diameter of a certain hole. Because they occur independently at many places across the surface of a growing film or coating, they tend to produce an analog of a cobblestone street with the cobbles being nodules or clusters of sp3 bonded carbon. Perhaps more interesting is that if prepared in the "medium" cobblestone version such as shown in the above figure, electricity is passed through it by a mechanism of hopping conductivity. drills are tipped (or solid I quess in small sizes)with carbide and are for special uses while the cobalt is used for most needs. , has a cobalt drill bit Sets for Every Kind of material end of the Persoz pendulum long time Normal.
