| Popis: | Sputter-coatings of carbon with 10% nitrogen incorporation grown to four different thicknesses of 10, 50, 100 and 200 nm were prepared by ion beam assisted depositing (IBAD) onto Si(111) substrates and then both surface characterized by an atomic force microscope (AFM) and nano-indented by a Thin Film Hardness Analyser. In sliding against a diamond pin at a relative humidity of 40%, CN 0.1 coated Si(111) showed an increased friction with a decrease in coating thickness. And the friction was also found to reach the maximum value of 0.171 for the coating with a thickness of 10 nm when the normal load was consecutively changed until 300 mN at a sliding speed of 10 μm/s. The traditional Bowden–Tabor model and the theoretical contact model proposed by Halling and Sherbiney however, are still found to be useful to discuss the observed behavior of friction variations of nano-scale CN 0.1 coated Si(111) from the viewpoints of coating thickness, adhesion and nano-indentation hardness, respectively. |
