| Outline of Final Research Achievements |
To realize release of stress concertation at edge of textured surface under dry sliding friction, the present study porpposed in-plain hetero-structured DLC films, which has a textured structure filled with DLC films with different hardness. By combining ionized vapor deposition, oxygen plasma etching, and plasma enhanced chemical vapor deposition, proposed structure was achieved successfully in an single vacuum system. Tribological properties of fabricated hetero-structured DLC films under dry friction showed the expected function of prior wear of soft phase DLC for the self-construction of textured structure. Structural design in view of wear properties of the in-plain hetero-structured DLC film was theoretically discussed using Archard’s and Bhushan’s wear equations.
