| Outline of Final Research Achievements |
Carbonaceous hard coatings as DLC and CNx are attracted keen attention to show not only high wear resistance but also ultra low friction that is less than 0.01 of friction coefficient under severe sliding condition that liquid lubricants can not work. We developed two novel evaluation systems as the evaluation method of transformed layer of carbonaceous hard coatings with a reflective spectroscopy and the evaluation method of surface energy of sliding surface of carbonaceous hard coatings with an Environmental Scanning Spectroscopy. The first evaluation systems showed that thickness, roughness and mechanical properties of transformed layer of coatings governed ultra low friction phenomena with a thin solid film lubrication theory. The second evaluation system confirmed that low surface energy of sliding scar provided low friction properties. From both clear findings for ultra low friction of carbonaceous hard coatings, new carbonaceous hard coatings as ta-CNx coatings was proposed.
