| Outline of Final Research Achievements |
The coating of ultra-low wear and friction film to existing bearing surface is one of the approaches to realize ultra-low wear and friction bearings required for small flywheel batteries. We established a technology to form amorphous carbon (DLC) films with different film quality, and made it possible to select film quality and characteristics according to the application. In addition, a laminated DLC/diamond film by depositing a DLC film on a polycrystalline diamond film and a multilayered DLC film consisted of DLC film layers with different film quality were fabricated, and these laminated films had low resistance of frictional wear and low aggressiveness to an opposite material compared with single-layer films. Improvement of tribology characteristics on bearings can be expected by selecting and using a suitable protective film
