Then frictional tests are carried out between CVD diamond coated balls and graphite. The results show that the MCD-graphite and NCD-graphite tribo-pairs exhibit comparable frictional coefficients, while the wear rate of graphite in MCD-graphite working pair is much higher than that of graphite in...

T he best known carbon crystal is diamond, whose hardness and high dispersion of light make it useful for industrial applications and jewelry. Under ambient pressures and at room temperature, however, the most stable form of carbon is graphite, which is used as an industrial lubricant and as ...

fundamental level, diamonds are composed of carbon atoms. Carbon is a unique element because it has four valence electrons, which allows it to form strong covalent bonds with other carbon atoms. This is why carbon can exist in a variety of forms, including graphite, graphene, and diamond. ...
Properties of filtered-ion-beam-deposited diamondlike carbon as a function of ion energy A highly tetrahedrally bonded form on nonhydrogenated amorphous carbon (a-C) is produced by deposition from filtered medium-energy ion beams. A range of su... P.,J.,Fallon,... - 《Physical Review B ...

The crystal data, collected reflections, and parameters of the final refinement are reported in Table 1. The structural graphic of the asymmetric unit was created with ORTEP [22] and for the other figures created with the DIAMOND [23]. Table 1. Crystal data and structure refinement details for...
A diamond-like carbon film is an amorphous carbon film with performances similar to those of a diamond film. Owing to good corrosion resistance, wear resistance and biocompatibility, DLC film has been obtained great attention in the field of biomedicine, especially artificial joints for more than ...
