With the help of a series of experiments such as Raman spectroscopy, FT-IR spectroscopy, AFM and nanoindentation , the DLC film has been recognized as hydrogenated DLC film and its tribologicul properties have been evaluated. The bull-on-disc testing results show that the hardness and the tribologicul properties of the DLC film produced by C^ ＋ ion beam- assisted deposition are improved significantly. DLC film produced by C ^＋ ion beam- assisted deposition is positive to have a prosperous tribologicul application in the near future.展开更多

The Ar+ ion energy used was from 4 to 12 keV. Several amorphous alloys were obtained in Hf-rich films and their compositions were located in a range of 50 similar to 80 at. pct Hf. The amorphization mechanism was also discussed.展开更多
