| 中文摘要 | Four kinds of nanocrystalline Mo(Si1-xAlx)(2) coatings with differing Al contents are prepared onto a Ti-6Al-4V substrates by a double cathode glow discharge apparatus. The microstructural features of the deposited coatings were characterised by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. These coatings are composed of the equiaxed C40-MoSi2 grains with the average grain size of similar to 5 nm. Nano-indentation measurements indicated that the hardness H, elastic modulus E and the H/E or H-3/E-2 ratio of the nanocrystalline Mo(Si1-xAlx)(2) coatings slightly increase with the increase in Al content. The tribological behaviour of the nanocrystalline Mo(Si1-xAlx)(2) coating sliding against a ZrO2 ceramic ball at room temperature has been compared using a ball-on-disc type tribometer under unlubricated conditions. Experimental results showed that the specific wear rates of the nanocrystalline Mo(Si1-xAlx)(2) coatings decrease with increasing Al content and are dramatically reduced by more than 1-2 orders of magnitude over the uncoated Ti-6A1-4V. The enhancement of wear resistance of the nanocrystalline Mo(Si1-xAlx)(2) coatings by Al additions is correlated with the increased mechanical properties and the forming oxide layer by tribochemical reactions. |
