“…The roughness will increase if the surface energy is high because the atoms need the high energy to agglomerate and form the film. Therefore, the final roughness of the DLC films is strongly dependent on the surface energy [35]. The result agrees well with the previous AFM results.…”

“…If the surface energy is high, the roughness increases, because the atoms need the high energy to be leagued and to form the film. In this situation, the final roughness of the DLC films is strongly related to the surface energy [19,20].…”

“…To improve the scalability of the PACVD technology and to reduce the cleaning requirements due to deposits on the deposition chamber walls, a new reactor design is used that has been described in [9]. By splitting the plasma chamber into a reactive gas chamber made of insulating material and an inert gas chamber containing the counter electrode, contamination of the counter electrode with deposits from the process gas is avoided and a significantly more stable process can be achieved.…”

Amorphous hydrocarbon (a-C : H) films have enormous potential as low friction, wear resistant coatings. Here, we present a plasma assisted chemical vapour deposition process for a-C : H that exhibits growth rates of 100 nm min -1 and higher. The tribological performance of the resulting a-C : H films has been studied experimentally by reciprocating sliding of an a-C : H-coated Si 3 N 4 ball on an a-C : Hcoated 100Cr6 steel substrate and by subsequent micro Raman spectroscopy of the wear track. Running-in of the coatings is observed and characterised by a rapid decrease in the friction coefficient accompanied by a significant increase in sp 2 hybridisation in the wear track. In order to gain a deeper understanding of the underlying running-in mechanisms, the sliding of two a-C : H films under a load of 5 GPa has been studied by classical molecular dynamics employing a range-corrected Brenner bond-order potential. The simulations reproduce the experimental trends and explain the running-in by a combination of smoothing and chemical passivation of both tribosurfaces. Consequently, both mechanisms should be controlled in order to produce tribological coatings for applications with optimum energy-efficiency.
