| Popis: | An environmental scanning electron microscope has provided direct evidence that the surface damage mode transitions occur during the room-temperature sliding of carbon nitride coating deposited on single crystal silicon substrate against a spherical diamond pin. Based on a detailed in-situ study of four kinds of thicknesses, i.e., 10, 50, 100 and 200 nm and with a bare substrate Si(111) for comparison, carbon nitride coatings showed that the sliding mainly consisted of `No grooving', `Grooving with no material removal' and `Grooving with material removal' three typical surface damage modes. The mode transitions were then be studied in the light of the critical loads and the critical groove depth corresponding to the summarized surface damage modes, and further discussed from the view point of coating thickness with a relation to the nano-indented hardness and a possible failure in the substrate. |
