Mechanical properties of high-density diamond like carbon (HD-DLC) films prepared using filtered arc deposition

Autor: Makoto Taki, Haruyuki Yasui, Shigeki Takago, Yushi Hasegawa

Publikováno v: Surface and Coatings Technology. 206:1003-1006

Because high density DLC (HD-DLC) films prepared using filtered arc deposition (FAD) systems possess high hardness, low friction coefficients, and a smooth surface, they have been good candidates for use in tribological applications. The aim of prese
