| Outline of Final Research Achievements |
The DLC thin films were prepared on metal substrates at 1073 to 1373 K under 1 atm. of methane and argon mixture gas. As metal substrates two kinds of Fe substrates with different purity at 99.5 and 99.99 % and SCM 440 substrate as one of steel materials. The surface compounds were analyzed with micro-Raman spectroscopy, hardness measurements and film thickness measurements with SEM. It was found that oxygen atoms migrate to the surface and to form Fe3O4 thin film on the Fe substrates with 99.5 % purity. The DLC films were successfully prepared even on Fe substrates with 99.5 % purity under optimum conditions. The intermediate compound formed between a metal substrate and the surface covering DLC film was analyzed with Raman spectroscopy.
