摘要
We have tested the tribological behaviour of steel probes with various diamond-like coatings in a vacuum shell and under various environments against steel. We obtained the coatings by plasma-assisted chemical vapour deposition. Experiments show good adhesion of these coatings to the substrate and good resistance to high shear stresses. This paper presents experimental results for several diamond-like coatings (DLCs), permitting an identification of the tribological behaviour of each coating structure. Coatings with a high electrical conductivity, which indicates the presence of graphite within the DLC, exhibit very good tribological properties: low friction coefficients and very low wear rates. Adsorbable gaseous environments lead to a decrease in the friction coefficient. Diamond-like coatings without the graphite structure show a very different tribological behaviour. The presence of water vapour or other active gases such as oxygen leads to an increase in the friction coefficient.
